旁瓣对消系统功率倒置自适应算法研究

Study of the Power Inversion Auto-adapted Algorithm About the Side-lobe Cancellation System

旁瓣对消技术是雷达中用来抑制旁瓣有源干扰的一种有效手段。文中在介绍旁瓣对消基本原理的基础上,给出了针对二元阵的旁瓣对消功率倒置自适应算法.该算法的核心是使输出功率最小。分析表明采用该算法的旁瓣对消系统可以很好地抑制从旁瓣进入的干扰,具有很好的抗干扰效果。

The side-lobe cancellation technology is an effective method for suppressing the side-lobe active disturbance.In the foundation of introducing the basic principle of the Side-lobe cancellation,This article produces the power inversion auto-adapted algorithm using in the side-lobe cancellation system In view of the dual.The core of this algorithm is to try hard to cause the output to be smallest.The analysis indicate that the side-lobe cancellation system of using this algo- rithm is possible to suppress the disturbance well which enters from the side-lobe,It has the good effect of antijam- ming.
