摘要
针对雷达在复杂电磁环境中受到异步干扰,造成性能下降的问题,提出了一种在频域范围内自适应检测异步干扰,进而在时域插值将其剔除的算法。与传统算法相比,该算法实现简单,运算量小,不仅可应用于地面雷达,也可用于机载雷达。实测数据的处理结果也验证了该方法的正确性和有效性。
To solve the problem of radar performance degradation caused by asynchronous interference in complex electromagnetic environment,this paper proposes an adaptive detection algorithm of asynchronous interference in frequency domain,and uses interpolation algorithm in time domain to eliminate it.Compared with the traditional algorithm,the algorithm in this paper is simple to implement with less computation,and can be applied not only to ground radar,but also to airborne radar.The processing results of real data also verify the correctness and effectiveness of this method.
