相邻周期反异步抗同频干扰方法分析

Analysis on The Method of Anti-jamming from Common Frequency by Against-asynchronism of Adjacent Periods

众所周知,现代战争都是立体战争,海战也是编队作战。但是编队作战面临的一个最大问题就是同频干扰,尤其是同型雷达的同频干扰.解决同频干扰的方法通常有载频错开反异步、相邻周期反异步等方法。从技术角度出发着重介绍了相邻周期反异步抗同频干扰的的原理、反异步准则及电路,并对该方法的反异步效果和局限性进行分析,对解决舰艇编队间的同频干扰问题有一定的借鉴作用。

As all known,modern warfares are all tridimensional operation,the sea warfare is the operation of ship formation too.But the most serious problem faced by ship formation operation is common frequency jamming,especially the common frequency jamming of same type radars.The general methods to solve the common frequency jamming are carrier frequency staggering against asynchronism,against asynchronism in adjacent periods,etc..From the aspect of technique,this paper mainly introduces the principle of anti-jamming from common frequency by against-asynchronism of adjacent periods,rule and circuit of against-asynchronism,and analyzes the against-asynchronism effect and limitation of the method,which has definite reference effect for solving the problem of common frequency jamming in ship formation.
