In this paper, a novel method of spatial resolution analysis for low frequency (LF) ultra-wideband (UWB) bistatic forward-looking SAR (BFSAR) is presented, which is based on the wavenumber domain spectrum support of point target. First, the imaging geometry and signal model of the LF UWB BFSAR are established, and the wavenumber domain spectrum support of the point target is analyzed. Then, the analytical expression of the spatial resolution of LF UWB BFSAR is derived. Finally, the simulation experiment is carried out, and the results prove the correctness and validity of the proposed method of spatial resolution analysis.

Radar tomography allows to build a two-dimensional image from one-dimensional functions obtained from radar returns. In this paper the possibility of usage of the reassigned spectrogram as well as different reassigned forms of time-frequency distributions in the Doppler radar tomography imaging is evaluated. The image is obtained from a multi-component signal with time-frequency modulations resulting from rotation. The algorithm of imaging with high resolution is tested on simulated data.

Test, measurement and verification of radar are necessary to ensure function according to specification and meet customer requirements. Extensive field tests are often required to test an entire radar system. This is not only expensive, but also requires a great deal of time. To reduce test complexity and cost, simulation techniques are used to recreate real-world conditions in a laboratory environment. Many subsystems can be tested by radar target generators simulating radar echo signals. They usually consider Swerling models, but struggle to simulate clutter, or in particular sea clutter. This paper introduces an approach to generate sea clutter with a state of the art vector signal generator. It shows common approaches modeling sea clutter and introduces a novel approach to combine the statistical models with a physical ocean surface model. This way, time and spatially correlated data that reproduces real-world sea clutter is generated, thus a cheaper, more time efficient way to conduct sea trials is presented.

In this paper front-end design for a Ka band milimeter wave (MMW) radar which consists of an antenna, a low noise amplifier (LNA) and a band pass filter is presented. The operation frequency of the designed system is between 24-25 GHz in Ka band. A high gain axially displaced elliptical (ADE) dual reflector antenna is employed on the antenna structure. ADE sub-reflector with 5 cm diameter is illuminated by a feeder horn and a main reflector 30 cm diameter parabola focuses incoming waves from the ADE sub-reflector. According to the simulation results narrow half power beam width (HPBW=30) and high gain (G=35 dBi) are obtained with good efficiency (%58). An HJ-FET that has low noise figure (NF<;1 dB) and high gain (>13 dB) is utilized to design a LNA. Double transistors are connected as cascaded to achieve higher transducer gain (Gt>19 dB). Matching circuits and feeder resonators are designed by microstrip lines to obtain low input and output VSWR (Vin<;2.1, Vout<;2.1). A microstrip band pass filter (BPF) is designed to receive required signals and to suppress other bands. The BPF is formed by combination of a radial stub low pass filter (LPF) and a short stub high pass filter. Low insertion loss (S21>-2.5dB) and low return loss (S11<;-15 dB) are aimed to take signal as lossless as at pass band. The simulated designs are manufactured and measured. It is seen that there are good agreements between measurement and simulation results.

Scattering center extraction from Synthetic Aperture Radar (SAR) data is a critical step in model-based SAR automatic target recognition (ATR). Three dimensional electromagnetic model (3D em-model) provides a concise and physically relevant description of target's electromagnetic scattering behavior by a set of representative scattering centers. In this paper, 3D em-model is used to guide scattering center extraction in SAR data. Firstly, 3D em-model is projected to the 2D measurement plane to predict the scattering region and the attributed parameters of each scattering center. Then, scattering center is extracted in the corresponding region predicted by 3D em-model with the model predicted parameters as an initial guess. Finally, a search strategy is adopted to optimize the scattering region and find the optimal parameters. Experiments using data simulated by a high-frequency electromagnetic code verify the validity of this method.

Frequency Modulated Continuous Wave (FMCW) Synthetic Aperture Radar (SAR) system is gaining more and more attention for earth observation with characteristics of compact size, light weight and low cost. A Ka FMCW miniature SAR system, called MiSAR, is given in this paper, which could be applied to the unmanned aerial vehicle (UAV) observation aero. We have taken the flight test. The real data has been processed based on the modified RD algorithm. Moreover, the motion compensation and PGA technology are used to improve the image quality. The feasibility of the Ka FMCW MiSAR system and the reliability of the imaging algorithm are all verified. On the other hand, the GMTI processing result is also presented based on the DPCA technology. The result proves the Ka FMCW MiSAR system's GMTI ability.

We numerically study degradation in the cross-polarized, complex-valued Interferometric Synthetic Aperture Radar (InSAR) coherence's magnitude (correlation) and phase due to electromagnetic (EM) wave penetration and guidance within planar-layered, (effectively) electrically anisotropic (i.e., electric field direction dependent) geophysical media. Specifically, we examine scenarios involving subsurface layers exhibiting electrical response given by deviated anisotropic tensors exhibiting low loss and high inter-layer dielectric contrast (i.e., strong subsurface wave guidance), as well as predominantly cross-pol specular interface scatter (XSIS)-based subsurface backscatter. We hypothesize that this scenario can occur within myriad layered geophysical structures containing media hosting a distribution of sub-wavelength, non-spherical inclusions with mean non-vertical orientation. Guidance-enhanced, XSIS-based backscatter we predict can dominate cross-pol InSAR observations (particularly at lower frequencies such as P-band) concerning these types of structures, leading (in the limit of stronger wave guidance) to rapid, inverse-quadratic degradation of correlation versus InSAR spatial baseline, as well as high and linearly divergent phase bias. Modeling the dominant cross-pol backscatter mechanisms adds another tool for Polarimetric InSAR (PolInSAR) data interpretation and inversion concerning sea ice and other complex layered geophysical structures which can contain media possessing effective anisotropic dielectric response.

The paper focuses on problem of detection of an agile target - a rocket, using passive radar. The main problem under consideration is improvement of detection capabilities of the radar by extending the integration time. As the target has small radar cross-section, any increase in signal-to-noise ratio is desirable. This can be achieved by extending the integration time used in the calculation of the crossambiguity function. This, however, is limited by the simplified model of target echo used in classical crossambiguity function and its mismatch with the actual target motion. The rocket observed by the radar accelerates very fast, which leads to the so-called velocity cell migration phenomenon, which limits the possible signal-to-noise ratio increase. In the paper extended crossambiguity function taking into account target acceleration is considered. The results of the algorithm are presented on data from DVB-T-based passive radar used for detection of a one-stage supersonic rocket.

Phase-coded radar signals and pulse compression offer the promise of exact range sidelobe cancellation. Using of these signals enables to decrease transmitted power of radar, to improve range resolution and resistance against various kinds of distortion or active jamming. The principal limitation of phase-coded radar signals is its sensitivity to the Doppler shift in case of moving targets. The techniques of the Doppler compensation in this case are effective. The Doppler compensation technique based on the Doppler Shift Emulator (DSE) with the multichannel correlation for binary phase-coded signals in presence of active noise jamming is presented in this paper.

In this paper is described an experimental passive localization system based on SDR (Software Defined Radio) components. This system is designed to measure Time Differences of Arrival (TDOA) of radar pulses between two platforms. For a TDOA system, time error between the two receivers must be kept very low, which requires a very accurate way to synchronize the time bases. In this purpose, a custom offline synchronization method is proposed. The overall performances of the system are analyzed. In a small scale outdoor experiment, it has been shown to perform TDOA measurements accurately. The performances measured during this experiment are then extrapolated to a more realistic electronic warfare scenario.
