Research of the Electronics Definite Direction Technology

With the development of electronic resist technology, the wireless definite direction technology becomes more and more important. By comparing the same external signal amplitudes which are received from two channel or more than two channels, ratio amplitude method realize the direction function. This paper analyzes and studies the influence of various system errors, and analyzes the multi-beam direction finding technology at the same time. The orientation of radar emitter which falls into different beam can also be measured.
