PD雷达探测低慢小目标性能分析

Influence Analysis of PD Radar Detecting LSS-Target

低空超低空突防的低慢小目标给现实防空带来了新的挑战。通过对频域PD模式下滤波器组杂波抑制能力的分析,得到了杂波环境中探测低慢小目标的改善因子。并且通过改善因子分析了L波段和S波段雷达探测运动目标的最小速度问题;进而对目标在不同速度、不同杂波环境下雷达的最大探测距离进行了仿真分析。评估了PD雷达探测低慢小目标的能力,为低慢小目标的探测研究提供了一定的参考。

With the development of the target which is low-altitude, slow and small（ LSS-target）, it brings new challenges to the daily air by low-altitude and low altitude penetration. Based on the frequency domain of PD mode, the improvement factor of detecting LSS- target in clutter conditions by construing the inhibiting capacity of filter bank is gained. Through the improvement factor simulation analysis of L-band and S-band radar detection, discussed minimum speed issues of detecting moving target and calculated the maximum detection range when the target speed varies in different clutter conditions. It evaluated the ability of detecting LSS- target, having guiding significance to the study of LSS-target.
