摘　　要：在实际电磁环境中，当目标飞行高度很低时，就会有相干干扰产生，而且相干干扰往往落在主瓣内．本文提出的将自适应理论与空间平滑理论相结合的自适应零点形成技术，对于相干干扰，特别是主瓣内的相干干扰有很好的抑制作用．In practical electromagnetic environment,coherent interference will be produced when the target is in low altitude.The coherent interference often presents the main beam.The spatial smoothing method is a perfect decorrelating method.We combine the idea of adaptation with the idea of spatial smoothing.The combination forms the technique of adaptive causing zero_point.The new combined method can suppress the coherent interference whether the interference presents the main beam.
