- W2354910174 abstract "For the disadvantage that the squint-looking and side-looking synthetic aperture radar( SAR)can not image the scene in front of the radar,a new millimeter-wave forward-looking SAR imaging algorithm is presented in this paper. The system architecture model is given and the system imaging principle is analyzed. Based on the spatial geometry and the pattern of echo signals,the target echo Doppler history is analyzed,the azimuth Doppler FM ratio is deduced and a Range-Doppler algorithm( RDA) is proposed.The phase compensation factors and range migration correction fomula are given. The imaging scene's size and azimuth imaging resolution are anlyzed in detail. Six points target imaging is simulated with MATLAB,64 × 64 points slice of the target peak center,peak-to-sidelobe ratio( PSLR) of azimuth and range are analyzed. Simulation results demonstrate the validity of the system and the direction resolution ratio can reach 2 meters. This system can be used in the field of investigation and guidance." @default.
