虚拟多普勒测向技术研究

Study on the Technique of Bearing Measurement Based on Virtual Doppler

文章首先分析虚拟多普勒信号产生原理，利用虚拟多普勒提出一种新颖的无源测向技术，给出了该技术的系统组成及实现方法；分析了虚拟多普勒信号处理所需要解决的几项技术；最后从原理样机出发，针对这一技术需要进一步研究的问题进行阐述，新的研究方向使极大提高测向精度成为可能。

The principle of the production of virtual Doppler signal is analyzed firstly. A new passive bearing measurement technique based on the theory of virtual Doppler is advanced, and the system composing and the realization of the technique are presented also. Then, several problems faced by virtual Doppler signal processing are analyzed. At last, based on the model machine, the problems which should be studied further according to this technique are expatiated. This new research makes it possible to improve the accuracy of bearing measurement hugely.
