| 摘 要： | 针对地波超视距雷达探海工作期间高频干扰严重海杂波强的特点,在阵列自适应波束形成时考虑了海杂波约束条件,改进了地波超视距雷达探海工作时的干扰抑制方法.改进方法使得自适应干扰抑制后,回波中一阶海杂波的时域相关特性不会发生破坏而在频域上"虚假"展宽,从而有利于后续处理中进行海杂波滤除和目标检测.最后使用OSMAR2000的实测数据对本文方法进行了检验.

| Abstract: | HF ground wave radar encounters intense interference and clutter during operation in ocean environment.This paper presents an improved adaptive beamforming algorithm introducing clutter constraints which do not destroy the natural temporal coherence of the first-order ocean clutter after interference suppression and benefit target detection in frequency domain subsequently.Performance of presented algorithm for interference suppression is evaluated using data acquired by OSMAR2000. |
