radar hole meaning in Chinese

雷达死区

Because of radio wave propagating along the ducts with enhanced fields on the order of the free - space field , the problems of the co - channel interference are more complicate for communication systems with the results of intersystem interference and the formation of other system , and therefore affecting the determination of the coordination distances or the optimization of the distribution and separation of delay , and for surveillance system such as radar system the problems can be radar holes or the extensions of detect range
对于通信电路，它使系统间的相互干扰问题变得复杂，既可能干扰其他系统又可能形成另外的系统，从而影响系统的有关参数如中继电路的最佳组合(分布、间隔)和协调距离，对于探测系统产生的则是雷达空洞、超视距探测等问题。这些问题对相关无线电系统特别是军事应用系统可能是致命的，因而以波导传播为代表的反常传播特性研究受到极大重视。
