This paper proposes a procedure for simulation of the temporally and spatially correlated low grazing angle sea clutter based on the statistical and correlated characteristics. The magnitudes are Pareto distributed and the temporal correlation characteristics in separated range bins are different from each other. Firstly, the memoryless nonlinear transform (MNLT) is adopted to directly simulate the Pareto distributed high resolution range profiles (HRRPs) of the temporally and spatially correlated sea clutter from coherent pulses. Secondly, by utilizing the approximately linear relationship between the central Doppler frequency and the magnitude of low grazing angle sea clutter, Doppler spectrum of each range bin is modeled. Then, the alternating projection (AP) approach is used to retrieve the phases of sea clutter with desired Doppler spectrum and given magnitudes. Finally, simulation results show the Pareto distributed temporally and spatially correlated sea clutter with desired spatial correlation function and range resolved Doppler spectra.

Following the increasing availability of reliable optical components, issued from the telecom domain, analog-optical links based on commercial modules have achieved performances which are close enough to system requirements to be extensively considered. With accurate understanding and modeling of these components, it has been demonstrated that RF photonics can be implemented to transmit and process RF signals in equipment. We report on recent progress concerning the development of several photonic modules to implement transmissions of radar (and electronic-warfare) signals in airborne environment.

In this paper we address the problem of multiple target tracking using passive radars. The fusion of data from several bistatic radars will be used to facilitate the detection of multiple targets. We propose a strategy for performing target localization and robustness against ghost target rejection in multistatic passive radars. We report the effect of our proposed technique on tracker performance in terms of probability of tracks loss, probability of false tracks and mean squared error.

This paper describes measurements of urban ground clutter made from the CSIR campus in Pretoria, South-Africa. The measurements were made using a wideband X-band radar. The radar clutter is analysed and a Doppler spectrum based clutter model is derived. The clutter model is optimised for implementation on a digital radio frequency memory (DRFM) based hardware in the loop (HIL) radar environment simulation system. The clutter model was compared to a different measurement in the dataset and it was found to provide an accurate fit to urban ground clutter for the low grazing angles under consideration. The coherent component matched that of the data, while the slow diffuse component matched well for low clutter bandwidths of less than 1 Hz. For clutter bandwidths larger than 1 Hz there was approximately a 2 dB mismatch in the spectral tails.

This paper demonstrates a method for doing coherent processing on navigation radar data. The radar transmit and receive signals are connected to a separate frequency conversion unit which transfers the X-band signals to an IF. These signals are digitized in two coherent channels and processed together. The system has been tested in field trials where pulse-Doppler operation against real targets, such as vehicles was demonstrated. Also measurements on synthetic targets with known Dopplers and ranges generated with the Digital RF Memory (DRFM) system EKKO II were conducted. Additionally a real-time processor has been developed. It is based on a board with analog-to-digital converters (ADC) and field programmable gate arrays (FPGA) and a computer with a graphical processing unit (GPU). Pulse compression and Hilbert transform are implemented in the FPGA while Doppler processing and CFAR are done in the GPU. An experiment demonstrating real-time moving target detection with this hardware has been conducted.

Modern active electronically steered antennas (AESA) operate in different platforms and systems. Inside AIRBUS Defence & Space, the focus on X-band antennas today is on airborne and fighter nose radars, in satellite based SAR antennas (synthetic aperture radar) for earth observation, and ground surveillance and security radars. Active airborne antennas are assembled with hundreds or even thousands of transmit/receive modules. This paper will describe the evolution of the so-called standardized module solution based on LTCC package technology with special regard to airborne applications and the correlated needs. This evolution especially contains significant optimization steps concerning area, weight and cost. By realization of an SMTR® Module suitable to a folded plank concept a significant reduction of installation depth could be achieved. As the module weight is dominated by its package, technology evaluation and implementation of advantageous concepts and materials was performed, here. Cost reduction is always a key focus of T/R module evolution as the modules still allocate a big part of antenna's production cost. Some steps have been realised here both on technology and component level. The next generation of AESA antennas will result in a combination of different operating modes within the same antenna front end, including radar, communication (data links), and jamming (electronic warfare, EW). This leads to enhanced demands especially towards the MMICs. The RF section of today's T/R modules for AESA applications is typically based on GaAs technology. During the last 10 years there was much progress in the development of disruptive semiconductor materials, especially GaN and SiGe BiCMOS, which have the potential to challenge or even replace the GaAs technology, here. This paper will describe and show this evolution through the last years and shall give an outlook towards future developments with regard to airborne applications.

Space target recognition is one of the radar's significant tasks. The separation of group targets is the basis of the target recognition when several targets are within a range cell of one radar beam. In this paper, a method for group targets separation based on high-order moment function and empirical model decomposition (EMD) is proposed. The first step is deriving the high-order moment function of the target echo signal, and then processing the imaginary parts of the high-order moment function with EMD method. We can achieve the separation of group targets according to the derivational IMF from the decomposition. Simulation is given to validate the effectiveness of the proposed method.

We consider the problem of detection of wall back plates, which intentionally or unintentionally block electromagnetic wave penetrations and prevent the waves from reaching the indoor scene. This renders the result of through-the-wall radar imaging incorrect and misleading. The proposed approach employs squint beamforming to avoid the strong direct returns from the front side of the exterior wall and allow the diffraction for the plate placed against or near to the back side of the wall to be detected. We aid squint beamforming with a wall removal technique based on eigenstructure of the data matrix. This technique is applied prior to imaging and mitigates sidelobe wall scattering residuals, which may still obscure the relative weak plate radar return.

This paper provides an overview of the Digital Video Broadcasting-Second Generation Terrestrial (DVB-T2) signal structure and using this signal in passive radar systems. The cross-ambiguity function (CAF) of the DVB-T2 signal is analyzed. The specific structure of the DVB-T2 signal is a reason of the unwanted deterministic peaks appearing in the CAF in addition to the desired reflected target echo. These undesired peaks produced by pilot carriers and guard intervals can mask the target echo and cause false alarms. A CAF correction method based on the modification pilot carriers and blanking guard intervals of the reference DVB-T2 signal is proposed. The total losses of the DVB-T2 signal power after correction is about 14% (-0.64dB).

This article examines the assessment of propagation conditions using data from a state-of-the-art, multi-function radar, namely the advanced radar technology integrated system testbed (ARTIST). The radar was situated at Wallops Island, USA and an extensive series of clutter recordings was conducted in 2010. The recordings are compared to site specific modelling using the naval electromagnetic environmental simulation suite (NEMESiS) software. Using this modelling software, it is shown that refractivity profiles predicted using local environmental measurements, in conjunction with analytical descriptions of evaporation ducts, do not result in a high fidelity reproduction of the clutter observed. Refractivity profiles recorded with radiosondes result in a better match to the data, but can produce an over-prediction of clutter. It is concluded that the most robust way to accurately assess propagation conditions is through a direct analysis of the radar clutter data, in conjunction with detailed modelling. This approach, duct inversion, is explored and is shown to have the potential of providing a quasi-real time assessment of propagation conditions, as required for environmentally aware radar.
