Detecting and Imaging of Moving Targets of Cluster Sar System
نویسنده
چکیده
Based upon the sparse array composed of cluster SAR satellites, this paper analyzes the space-time and space-frequency characteristic of the received signal in detail, and proposes an algorithm for the moving targets detection and imaging based on array signal processing and Wigner-Ville Distribution (WVD). The results of theoretical analysis and simulation show that the cluster SAR system can achieve the targets SAR image even if the targets is being moving slowly.

Microwave Imaging Using SAR
Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
متن کاملUnambiguous Imaging of Static Scenes and Moving Targets with the First Chinese Dual-Channel Spaceborne SAR Sensor
Multichannel synthetic aperture radar (SAR) is a breakthrough given the inherent limitation between high-resolution and wide-swath (HRWS) faced with conventional SAR. This paper aims to obtain unambiguous imaging of static scenes and moving targets with the first Chinese dual-channel spaceborne SAR sensor. We propose an integrated imaging scheme with the dual-channel echoes. In the imaging sche...
متن کاملMoving target detection in foliage using along track monopulse synthetic aperture radar imaging
This paper presents a method for detecting moving targets embedded in foliage from the monostatic and bistatic synthetic aperture radar (SAR) data obtained via two airborne radars. The two radars, which are mounted on the same aircraft, have different coordinates in the along track (cross-range) domain. However, unlike the interferometric SAR systems used for topographic mapping, the two radars...
متن کاملIntegrating 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 ...
متن کاملDetecting Moving Targets in SAR Via Keystoning and Phase Interferometry
We require continuous and unambiguous radar tracking of surface moving targets for several minutes to target and engage moving targets. Conventional radar surface moving target trackers typically drop or confuse tracks after only a short time. If we can couple state of the art motion-compensated Synthetic Aperture Radar (SAR) techniques with advanced Surface Moving Target Information (SMTI) tec...
