摘　　要：在自适应阵列天线抗干扰的一些应用环境中 ,往往需要天线方向图在干扰的到达方向上形成宽的零陷以增强算法的稳健性。该文对一种宽零陷天线方向图合成方法进行了研究 ,提出了通过对零点矩阵加权处理 ,使不同干扰方向上的零点深度可以分别调节的改进方法 ,降低了方向图的畸变程度。It is often desirable to widen the interference null width in an adapted pattern to impart robustness into the adapted array in some real environments. In this paper, a new pattern null depth adjustment method is derived by weighting the null-matrix, so that it decreases the pattern's distortion. Moreover, this method is simple and easy to process. Computer simulation results demonstrate the effect of improvement.
