摘要
本文分析了弹头与目标相对运动背景下,步进频回波信号的相位特征,讨论了相位畸变对目标检测所带来的影响。以此为依据,着重分析了步进频信号的运动补偿思路,并进行了仿真分析,仿真结果进一步验证了速度补偿的必要性。
The phase characteristic of stepped frequency echo signal at relative moving background of of warhead and target is analyzed; and the effect on target detection caused by phase distortion is discussed; On basis of this,the motion compensation idea of stepped frequency signal is analyzed emphatically and the simulation analysis is performed. The simulation result verifies the necessity of speed compensation further.
