摘　　要：针对目前的罗兰C接收机在抑制窄带干扰方面的缺陷,在NBI频率点检测技术的基础上,对零限幅陷波技术抑制NBI、修正的零限幅陷波技术抑制NBI、自适应干扰对消技术抑制NBI进行了分析和仿真,并对仿真结果进行了对比讨论。This paper based on the point of frequency of narrow band interference detection technique,it is dead againstthe limitation of narrow band interference suppression technique in Loran-C receiver, it mainly discuss zero-limit range eliminate wave and amend zero-limit range eliminate wave and the adaptive interference each other eliminate technique in narrow band interference suppression in Loran-C receiv- er,in the end of paper,the results of simulation are analyzed and compared.
