摘要
介绍了双基地前向散射雷达侧影成像的原理 ,分析了该雷达回波中目标信号和杂波的时频特性 ,提出了利用小波分析剔除该雷达回波中杂波的方法 ,然后提出了利用时频分析估计目标径向运动参数的稳健的运动补偿算法 。
A principle of shadow imaging for bistatic radar based on forward scattering is introduced. Joint time frequency characteristics of target signal and ground clutter are analyzed, then a method of eliminating ground clutter in bistatic radar echo by wavelet analysis is presented. A robust motion compensation method to estimate radial motion parameters of target by time-frequency analysis is presented. Finally, the effectiveness of these methods is shown by the results of computer simulation.
