一种适用于双通道星载SAR的动目标检测技术

实用的星载SAR/GMTI系统仍处于研制阶段,从工程实现的角度研制一发双收的星载SAR/GMTI处理系统是可行的,仿真结果表明这种体制能够有效抑制地杂波,增强信杂比,从而检测出被地杂波淹没的慢动目标信号,并进行动目标参数估计.运用论文给出的原理和检测方法对机载SAR/GMTI战场侦察雷达试验系统录取的动目标数据进行了实际验证,获得了多帧连续可靠的真实动目标轨迹.

A Moving Target Detection Method for Dual-Aperture Spaceborne SAR

Developing spaceborne SAR-GMTI system is concern by many countries,in view of engineering realize,we presented a spaceborne SAR-GMTI processing system model which use one aperture for transmitter and two receiver,computer simulation results show that the system can suppress clutter effective and enhance signal-to-clutter ratios(SCRs) sharply,so the radar system can easily estimating parameters and detecting ground slowly moving targets even they were embed in clutter.Follow the paper's method,after processing a part of the actual measured data recorded from an airborne battlefield reconnaissance radar designed by ECRIEE,which take the first airborne SAR-GMTI tested in China,we get a continuous true track of ground slowly moving targets.
