一发三收天线无线电引信定向探测

内容简介：导弹定向引信天线均为发收成对配置,而炮弹尚未见定向引信。为了给炮弹定向起爆的需求预作准备,提出了基于10 GHz频段的一发三收天线无线电引信定向探测方法。该方法根据接收信号强度在空间的分布情况实现定向探测,仿真表明该方法在信噪比高于0 dB以上可获得90%以上的检测概率,虚警概率趋于零。

Abstract：All missile directional fuze antennae equip pairs of transmitting and receiving antennae,while ammunition round have not directional fuze so far.Introduces a method on radio fuze directional detection to one transmitting and three receiving antennae based on 10 GHz frequency band in order to prepare for explosion-orientedly ammunition round.The method realizes directional detection in accordance to receiving signals intensity distribution in space.It is proved by simulation that the method can gain above 90% detection probability and false alarm probability tends to zero with above 0 dB signal to noise ratio.
