摘要
对常规和差测角方法,当脉冲多普勒雷达面临主瓣干扰时,在采用自适应空域干扰抑制算法完成干扰抑制后,测角曲线会发生畸变,从而造成雷达测角性能下降。提出了采用子阵多重信号分类算法进行目标与干扰同时精确测角以及同时完成目标检测的技术,该技术可以有效避免主瓣干扰下和差测角曲线变形问题。通过计算机仿真证明了该方法的有效性。
For pulse Doppler radar, the curve of the angle measurement using sum and difference beam distorts after the main-lobe jamming suppression. The multiple signal classification method in subarray level is proposed to accomplish the angle measurement of jamming and target simultaneously. Target detection and direction estimation are carried out at the same time. Its efficiency is validated by computer simulation.
