无线电引信超低空性能实现的关键就是抑制海杂波,提取出目标信号。目前常用的距离波门截止技术和频谱识别技术所能达到的超低空性能还分别有其不足之处。文中针对以上两种技术的缺点,从海杂波对消的角度出发,提出了一种简单而有效的海杂波抑制方法。 The key to achieve ultra low-altitude performance of radio fuze is to suppress sea clutter and extract the target signal. At present, the common low-altitude performance that Wavegate cut-off technology and spectrum identification technology can achieve respectively has its shortcomings. In view of the shortcomings of the above two techniques, a simple and effective sea clutter suppression method is proposed based on the cancellation of sea clutter.
