摘要
根据SAR系统GMTI模式下点源目标 (固定或运动 )的特点 ,分析、计算了目标回波信号的多普勒质心、调频斜率和扫描波束的多普勒谱宽 ,讨论了载机平台位置和姿态的变化对系统的影响。文中按照分析和讨论的结论 ,提出了GMTI模式运动目标数据处理的解决方案。
According to the features of point source targets (fixed or moving) for SAR with GMTI, the Doppler frequency center, linear frequency modulation rate and Doppler spectrum are analyzed and calculated, and impact of variation of the location and the posture of the SAR carrier platform is discussed. As the result of the analysis and discussion, a solution of GMTI data processing for moving target is proposed.
