چکیده

Displaced phase center antenna (DPCA) and along-track interferometry (ATI) are two classical techniques used to determine synthetic aperture radar-ground moving target indication (SAR-GMTI) field. According to the research from now, conventional DPCA is superior to ATI[1],[2]. But, even the conventional DPCA is not all that could be desired. This paper proposes the algorithm called region-correlation ratio weighted of DPCA (WDPCA) algorithm. We introduce a novel concept of region-correlation ratio weighted so that the proposed algorithm promotes the detection performance compared with conventional DPCA. Some numerical experiment are also provided to prove the new algorithm has a better performance than the conventional algorithm.

SAR Ground Moving Target Indication Based on Relative Residue of DPCA Processing

For modern synthetic aperture radar (SAR), it has much more urgent demands on ground moving target indication (GMTI), which includes not only the point moving targets like cars, truck or tanks but also the distributed moving targets like river or ocean surfaces. Among the existing GMTI methods, displaced phase center antenna (DPCA) can effectively cancel the strong ground clutter and has been w...

Integrating Space-time Processing into Time-domain Backprojection Process to Detect and Image Moving Objects

The ability to detect and image moving targets, even surrounded by strong clutter on the ground, makes Synthetic Aperture Radar (SAR) more and more important for Ground Moving Target Indication (GMTI). Moving target detection is most commonly performed by GMTI radars based on antenna array solutions without imaging capability while SAR systems do not facilitate detecting the presence of moving ...

SAR and Moving Target Indication

Synthetic aperture radar provides high-resolution images of the non-moving ground scene, but fails to indicate and position moving objects. A short review of the motioninduced effects occurring in SAR images will open this lecture. Like in special airborne MTI systems, the solution to the SAR MTI problem is to use an array of antennas or subapertures and several receiving channels to cancel the...
