文章基于机载双基地雷达空间位置关系,分析了对应的雷达回波信号和多普勒谱的展宽度特性,并提出了在飞行试验中如何利用航线和速度的调整进而控制地面散射杂波因天线波束宽度而引起的多普勒频谱的展宽,实现对地面慢速目标进行有效检测。
Based on the spatial positional relationship of airborne bistatic radar, the paper analyzes the corresponding width characteristics of radar echo signal and Doppler spectrum, and proposes how to adjust the clutter due to the flight path and velocity in the flight test Antenna beam width caused by Doppler spectrum broadening, to achieve the effective detection of slow targets on the ground.
