Single-Channel UWB SAR Ground Moving Targets Detection Method Using Change Detection Based on Single-Pass Sub-Aperture Images
Ultra-wide Band Synthetic Aperture Radar (UWB SAR) operating in VHF/UHF band has the capabilities in high resolution imaging and foliage penetration. In this paper we exploit its large beamwidth and propose a new ground moving target detection method for single-channel UWB SAR using change detection based on single-pass sub-aperture images, which is called sub-aperture SAR images change detection (SASICD). When we select several sub-apertures with appropriate size to form images, the moving target can focus on different positions in accordance with the centers of the sub-apertures, while the stationary one remains the same. The SASICD attempts to distinguish this difference and estimate the target’s position and velocity precisely. The effectiveness of the method is illustrated when we process the UWB SAR real raw data.
