摘　　要：全极化测量雷达是雷达发展的一种趋势,然而现有极化测量方法的性能已不能满足要求。本文提出了一种采用复合编码信号的同时极化测量方法,该方法分别用内层码和外层码实现良好的自相关特性和互相关特性,在多目标、多发射极化的情况下具有明显优势,为极化信息处理特别是极化抗干扰技术的发展解决了极化测量方面的技术瓶颈。Polarimetric radar is a major development tendency of radar. With the development of the polarization information pro- eessing theory, existing polarization measurement method has been unable to meet demand. A simultaneous polarization measurement method using composite coded signal is proposed in this paper. This method separately uses the inner layer code and the outer layer code to realize the good autoeorrelation characteristic and the mutual correlation characteristic, and has the special superiority in the multi- targets and multi-emission-polarizations situation. This method solves the radar polarization measurement＇ s technology bottleneck for the development of polarization processing especially polarization anti-jamming processing.
