- 窄带干扰是雷达系统常见的干扰形式,会严重影响雷达的工作质量。针对雷达系统的强窄带干扰抑制问题,采用基于自适应的频域陷波技术的抗干扰算法,算法自适应生成判决门限,判断干扰所在位置,并通过对干扰与LFM雷达信号重叠部分谱线处理抑制干扰。详细介绍方法的原理和处理流程,主要论述判决门限的生成方法和谱线处理的方法。用Matlab对该方法进行仿真与分析。最后用FPGA实现算法。算法能够较好地抑制LFM 信号中的大功率窄带干扰,并且具有一定的自适应性。
- Abstract:
- Narrow Band Interference is a common form of jamming in radar system jamming, It will seriously reduce the work quality of the radar, How to suppress narrow band interference is an important subject in the field of radar ECCM. Aimed at the problem of strong narrowband interference suppression for radar, the authors propose a radar ECCM algorithm based on adaptive frequency domain notch. This method uses the adaptive filtering method, detects the interference location,and suppresse the interference by processing the overlap of the interference and the LFM radar signal. In this paper, the principle and process of the method are introduced in detail, The method of generating decision threshold and the method of processing spectral line are mainly discussed,and the simulation and analysis of the method is carried out with Matlab.At last,the algorithm is realized by FPGA. This algorithm can suppresse the strong narrow band interference in LFM signal, and has a certain adaptability.
