摘要
在超视距雷达的发展历程中,计算机仿真技术的出现有力地推动其技术的发展。海杂波作为超视距雷达探测中的一个主要干扰因素,严重影响到相应技术的发展。在传统计算机仿真技术中,很少考虑到滤波算法对信号的影响,这就造成目标信号在通过计算机仿真后产生较大的失真。本文针对上述计算机仿真的不足,将信号的纠正过程引入计算机仿真算法中,达到海杂波抑制和信号修正的双重目的,并通过实验与传统计算机仿真结果进行对比,较好地体现出本文所设计滤波算法的优越性。
In the development of over-the-horizon radar, the advent of computer simulation technology promotes the development of its technology effectively. Over-the-horizon radar is often disturbed by strong sea clutter in the detection process, seriously affecting the development of the corresponding technology. As the traditional sea clutter filter considers only the suppression of sea clutter and rarely takes into account the effect of filtering algorithm on target signal in the computer simulation technology, the tar- get echo produces great distortion after the computer simulation. This paper aims to solve the above problems by introducing the correct process of the target signal into the algorithm of the computer simulation technology. By the correction of the filter parameter, the sea clutter is suppressed and the filtering signal is corrected. In the actual simulation experiments, comparing the results with traditional computer simulation technology, we have also proved the superiority of this new filtering algorithm.
