针对机载雷达对低速目标检测能力较弱的问题，分析了常规处理和ΣΔ-STAP 的原理，通过仿真，比较了常规处理和ΣΔ-STAP方法的改善因子曲线、平均输出杂波加噪声功率以及空域频响图，并且用实测数据对两种方法的效果进行了验证。结果表明，ΣΔ-STAP能够降低杂波输出，尤其降低主杂波输出，使主杂波变窄，能够增强机载雷达低速目标检测能力。

The theories of adaptive array processing and ΣΔ-STAP are talked about in this paper, and we compare the im-provement factor, average output power of clutter and noise and frequency response graph of space. Additional, we test two methods using the measured data. Results demonstrate ΣΔ-STAP have a high performance in clutter-suppression and im-provements in low speed ground target detection.
