研究了和差空时自适应处理(∑△-STAP)在机载火控雷达中的应用,针对在实际处理中,由于地面杂波的非均匀性将严重影响∑△-3DT算法处理的效果,在此结合非均匀环境STAP处理,采用功率选择训练的非均匀处理方法,降低了STAP处理代价,实际处理结果显示,该处理显著提高杂波估计和抑制性能,较大提高了动目标的检测性能,文中还对目标径向速度的估计和方位定位问题进行研究,为该技术用于机载火控雷达地面动目标检测创造了条件。
The application of ΣΔ-STAP in airborne fire-control radar is studied. In the actual processing, the effect of ΣΔ-3DT processing is seriously affected by the inhomogeneity of ground clutter , Which combined with non-uniform environment STAP processing, the use of power selection training non-uniform processing method to reduce the cost of STAP processing, the actual treatment results show that the processing significantly improve the clutter estimation and suppression performance, greatly increased the detection of moving targets Performance, the paper also studies the target radial velocity estimation and azimuth localization, which has created the conditions for the technology to detect ground moving targets of airborne fire control radar.
