摘要
针对Loran-C接收机窄带干扰的问题,要想有效的抑制NBI,首先要计算NBI的频率点,而对于罗兰C系统来说,其覆盖范围达到1000km以上,在这么大的范围内,随着接收机在不同的位置,NBI的频率点肯定是变化的,同时干扰的数量也是变化的,针对这种情况,本文讨论了窄带干扰频率点的检测方法。
In order to suppress narrow band interference, the point of frequency of narrow band interference must be detected, The system of loran-c can cover with 1000 rnilimeters, in this large area, when the locality of receiver is different, the point of frequency of narrow band interference is different, at the same time, the amount of interference is also different, This paper discuss the means about detection the point of frequency of narrow band interference.
