Coherent detection schemes have been shown to offer performance benefits over non-coherent techniques in the maritime radar context. To further improve performance, the use of sparse representations with judiciously selected dictionaries has been proposed as a method to separate target returns from surrounding sea clutter. This paper exploits a robust frequency estimation scheme to effectively separate the target from clutter and noise. The approach offers two advantages: (1) it does not require a dictionary to be designed to support the scheme and (2) the scheme is capable of estimating multiple frequencies, thus suitable for targets with multiple Doppler components. In this work, we use both real and simulated sea clutter with synthetic targets for evaluation. It is found that the proposed technique can improve performance over traditional coherent detection for both point targets and more complex targets with multiple frequency components.
在海事雷达环境中,相干探测方案已被证明具有优于非相干技术的性能优势。为了进一步提高性能,提出了使用稀疏表示和明智选择的字典作为分离目标回波和周围海杂波的方法。本文利用一种鲁棒频率估计方案,有效地将目标从杂波和噪声中分离出来。该方法具有两个优点:(1)不需要设计字典来支持该方案;(2)该方案能够估计多个频率,因此适用于具有多个多普勒分量的目标。在这项工作中,我们使用真实和模拟海杂波与合成目标进行评估。结果表明,对于点目标和具有多频率成分的复杂目标,该方法都能较传统的相干检测提高检测性能。

Traditional dynamic programming based track-before-detect (DP- TBD) methods may suffer performance loss due to the suboptimal preprocessing. In this paper, a DP-TBD method based on preprocessing with pseudo-spectrum is proposed. For each cell in the observed image, a pseudo-spectrum is constructed around the cell itself with measurement value as its peak according to a point spread function. Samples of the pseudo-spectrum are added onto corresponding cells in the current frame. This facilitates improved performance through the intraframe integration by using spilled target echo energy. Then, dynamic programming procedure is performed for mul-tiframe integration. The pseudo-spectrum based preprocessing is presented, and energy integration procedure for the proposed DP- TBD is provided in detail. Theoretical analysis and simulation result demonstrate the validity of the proposed method.
传统的基于动态规划的检测前跟踪(DP- TBD)方法由于预处理不够理想,会造成性能损失。提出了一种基于伪谱预处理的DP-TBD方法。对于观测图像中的每个单元,根据点扩散函数,以测量值为峰值,围绕单元本身构造伪谱。伪光谱的样本被添加到当前帧中相应的单元中。这有助于通过使用溢出目标回波能量的帧内集成来提高性能。然后,对多帧积分进行动态规划。提出了基于伪谱的预处理方法,并详细介绍了该方法的能量积分过程。理论分析和仿真结果验证了该方法的有效性。

Radars monitoring small targets often must increase their integration times to achieve sufficient signal-to-noise ratio (SNR) for maintaining a viable track. These longer integation times can prevent micro-Doppler signature extraction and instead result in Doppler signatures consisting of spectral lines to the radar's higher-level processing. Whether the radar operates in the micro-Doppler or spectral line regime depends on both radar parameters (e.g. waveforms, wavelengths and integration times) as well as target parameters (e.g. rotor length, rotational frequency, target reflectivity and geometry). Additionally, understanding the transition region between these regimes can further aid target recognition algorithms. This paper uses modelling, simulations and experimental data to refine the understanding of how a particular radar will observe a target Doppler signature in either of these regimes, highlighting the transition region between the two.
监测小目标的雷达往往需要增加积分次数,以获得足够的信噪比(SNR)来维持可行的航迹。这些较长的集成时间可以阻止微多普勒特征提取,而是导致由谱线组成的多普勒特征用于雷达的高级处理。雷达是否在微多普勒或谱线状态下工作取决于雷达参数(例如波形、波长和积分时间)以及目标参数(例如转子长度、旋转频率、目标反射率和几何形状)。此外,了解这些机制之间的过渡区域可以进一步帮助目标识别算法。本文使用建模、模拟和实验数据来完善对特定雷达如何在这两种情况下观察目标多普勒特征的理解,突出了两者之间的过渡区域。

This paper presents a radar and camera sensor fusion framework as a vulnerable road user (VRU) perception system that can automatically detect, track and classify different targets on the road. The first module of the system performs a spatial-temporal alignment on a common plane of detections provided by the radar signal processing and video processing modules. The second module is dedicated to data association of the aligned detections. A centralized fusion algorithm takes the current aligned detection set (locations and labels) as inputs from both sensors and performs multi-object tracking with a joint probabilistic data association (JPDAF) algorithm underlying the Kalman filter. The proposed radar/camera fusion system is experimentally evaluated through multi-object tracking scenarios. The experimental results demonstrate its reliability and effectiveness compared to a single sensor system

This paper deals with the joint design of transmit waveform and receive filter to improve the clutter rejection capability for non-uniform pulse repetition interval (NUPRI) airborne radar. Specifically, a multipulse echo model accounting for a moving point-like target and signal-dependent clutter is first established. Then the echo is processed via the matching filter and the windowed Doppler filter bank to obtain the two-dimensional range-Doppler plane. Further, the integrated sidelobe level of clutter (ISLC) that spreads the region of the target of interest in the plane is considered to minimize forcing constant modulus constraint on the waveform. To solve the resultant nonconvex problem, the Sequential Greedy Optimization Algorithm (SGOA) through alternately updating the receive filter and transmit waveform is proposed to monotonically decrease ISLC to converge. In each iteration, the iterative algorithm based on coordinate descent (CD) framework and the sequential convex approximation algorithm are, respectively, explored to obtain the transmit waveform and receive filter. Finally, the performance of the proposed algorithm is assessed through numerical simulations showing its capability to suppress signal-dependent clutter.
为了提高非均匀脉冲重复间隔(NUPRI)机载雷达的杂波抑制能力,研究了发射波形和接收滤波器的联合设计。具体地说,首先建立了考虑运动点目标和信号相关杂波的多脉冲回波模型。然后通过匹配滤波器和加窗多普勒滤波器组对回波进行处理,得到二维距离-多普勒平面。此外,杂波的集成旁瓣电平(ISLC)扩展了目标在平面上的区域,以最小化对波形的恒模约束。为了解决由此产生的非凸问题,提出了顺序贪婪优化算法(SGOA),通过交替更新接收滤波器和发射波形来单调降低isc以收敛。在每次迭代中,分别探索了基于坐标下降(CD)框架的迭代算法和序贯凸逼近算法来获得发射波形和接收滤波器。最后,通过数值模拟对该算法的性能进行了评估,显示了其抑制信号相关杂波的能力。

Since the road infrastructure is an important factor for the economy and safety, the continuous monitoring of the road condition is a necessity. Compared to the widely used costly, time consuming and labour-intensive road condition monitoring using measurement vehicles all over the country, the potential of SAR polarimetry to remotely monitor the road surface roughness, cracks and potholes are investigated in this study. The polarimetric analysis of fully polarimetric X-band radar datasets acquired over the Kaufbeuren test site with DLR's airborne sensor F-SAR revealed that the anisotropy and coherency matrix (T3) elements are sensitive to the road surface roughness and can be used to retrieve the vertical surface roughness. The cross-polar sigma nought images show a considerable increase in their magnitude over the cracks and potholes on the road surface. The initial experimental results obtained from this study are discussed in this paper.
由于道路基础设施是经济和安全的重要因素,因此对道路状况的持续监测是必要的。与目前国内广泛采用的昂贵、耗时、劳动密集型的道路状况监测方法相比,本研究探讨了SAR偏振法在道路表面粗糙度、裂缝和坑洞远程监测中的潜力。利用DLR机载传感器F-SAR对Kaufbeuren试验场全偏振x波段雷达数据进行极化分析,结果表明各向异性和相干矩阵(T3)元素对路面粗糙度敏感,可用于提取垂直路面粗糙度。交叉极坐标的西格玛零图像显示,在路面上的裂缝和坑洞上,它们的大小有相当大的增加。本文对初步实验结果进行了讨论。

This paper presents the joint design of discrete slow-time radar waveform and receive filter, with the aim of enhancing the Signal to Interference and Noise Ratio (SINR) in phase coded radar systems for vital-sign monitoring. Towards this, we consider maximizing the SINR at the input of the vital-sign estimation block, when transmitting hardware efficient Mary Phase Shift Keying (MPSK) sequences. This multi-variable and non-convex optimization problem is efficiently solved based on a Minimum Variance Distortionless Response (MVDR) filter, with the Coordinate Descent (CD) approach for the sequence optimization, and the obtained results have shown attractive interference suppression capabilities, even for the simple binary case.

The positioning ability of the DOA estimation algorithms in array signal processing depends on the correct selection of snapshot data including the target echo signal. However, in the scene with low signal-to-noise ratio (SNR), the CFAR method, which is frequently used before DOA estimation, cannot effectively discover the snapshot data containing the targets, resulting in the loss of the target. In this paper, we propose a multi-frame DOA (MF-DOA) estimation algorithm, which implements multi-frame energy accumulation and snapshot data extraction based on the introduced target motion model so that the weak moving targets can be effectively located. The simulation data and real MIMO radar data are processed, and the results show that the MF-DOA algorithm has good ability to excavate weak moving targets and extend the radar detection range.
阵列信号处理中DOA估计算法的定位能力取决于包括目标回波信号在内的快照数据的正确选择。然而,在低信噪比的场景下,在DOA估计之前经常使用的CFAR方法无法有效地发现包含目标的快照数据,导致目标丢失。本文提出了一种多帧DOA (MF-DOA)估计算法,该算法基于引入的目标运动模型实现多帧能量积累和快照数据提取,从而有效定位弱运动目标。对仿真数据和MIMO雷达真实数据进行了处理,结果表明,MF-DOA算法具有较好的挖掘弱运动目标的能力,可以延长雷达的探测距离。

The simulation data and real MIMO radar data are processed, and the results show that the MF-DOA algorithm has good ability to excavate weak moving targets and extend the radar detection range.","PeriodicalId":161046,"journal":{"name":"2020 IEEE Radar Conference (RadarConf20)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126768512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radar communications (RadCom) is a spectrally efficient way for removing automotive radar interference and thereby enhancing reliable radar sensing, via a single hardware for both radar and communications. When interference coordination does not use all the RadCom resources, opportunities for communicating additional data arise. We propose a new communication protocol, termed RadNet (for radar network), which forms a vehicular ad-hoc multi-hop network by automotive radars in a distributed manner. Simulation results obtained for high-way use cases show that RadNet can enable several Mbps data links without degrading the radar performance.
雷达通信(RadCom)是一种消除汽车雷达干扰的频谱有效方法,从而增强可靠的雷达传感,通过雷达和通信的单一硬件。当干扰协调不使用所有RadCom资源时,就有机会通信额外的数据。我们提出了一种新的通信协议,称为RadNet(雷达网络),它以分布式的方式由汽车雷达组成车载自组织多跳网络。高速公路用例的仿真结果表明,RadNet可以在不降低雷达性能的情况下实现几个Mbps的数据链路。
