摘    要:高频地波超视距雷达在舰载条件下探测舰船目标面临着诸多挑战.其中之一是雷达平台运动导致的一阶Bragg谱线的展宽将淹没多普勒频率落入此展宽区的目标.本文首先利用合成孔径原理分析了展宽谱的性能.在此基础上,论证了通过空间滤波对消海杂波而留存目标回波的实际可行性.最后给出的实验结果进一步证明了本文所提方法的有效性.

关 键 词:超视距雷达  海杂波对消  合成孔径  目标检测

Abstract:For HF ground wave OTH radar to detect ship targets in the shipboard environment is faced with a range of technical challenges.One of them is that the spreading of the first order Bragg lines will obscure targets with Doppler frequencies within the range of this spreading.In this paper,the properties of the spreading are firstly analyzed with the aid of the synthetic aperture theory.On this basis,the feasibility of canceling sea clutter and retaining target returns by the space filtering is proved.The experimental results presented in the end further demonstrate the effectiveness of the technique put forward in this paper.
Keywords:OTH radar  sea-clutter-canceling  synthetic aperture  target detecting
