摘　　要：测定来波的方向,可以通过测量接收实时信号的幅度或者相位等信息来实现。但是均需要进行更复杂的信号处理。因此,提出了一种新的方法,基于两个接收信号强度的比值关系来确定信号源的方向。该方法采用负反馈的方式,根据两个接收信号强度的比值关系对指向进行修正。在实验中完成了信号源方向的测量,精度能达到4°以内。The direction of the incoming wave can be determined by measuring the amplitude or phase of the received real-time signals.However,more complex signal processing should be finished.Therefore,a new method is proposed to determine the direction of the signals sources based on the ratio relationship between the intensity of the two received signals.The method uses negative feedback modes to correct the direction according to the ratio relationship between the intensity of the two received signals.In the experiment,the signal source direction is measured,and the precision can reach within 4°.
