摘　　要：相控阵雷达导引头在搜索阶段不论采用哪种扫描方法,均存在波束偏置测角的情况,而基于雷达测角的基本原理:波束偏置时测角误差较大,导致截获波束指向偏差较大,有一定概率导致目标截获失败。针对此问题本文提出一种可以有效提高相控阵导引头截获概率的波束指向修正方法。通过数字仿真分析得出利用修正后的波束指向完成目标截获可以有效提升导引头的角度截获概率。Regardless of scanning method selection,beam-offset angle measurement often existed during searching process for phased array radar seeker.Due to the basic principle of radar angle measurement,the angle measurement error was larger if the beam-offset occurred,resulting in a large pointing deviation of the beam,which has a certain probability to lead to capture failure.To address this issue,a method was introduced based on beam pointing correction which can effectively improve the capture probability of phased array seeker.It was verified through digital simulation analysis that the angle capture probability of the seeker can be effectively improved by using the modified beam pointing to capture the target.
