摘　　要：虚拟极化技术是实现雷达极化状态自适应变化的有效方法。文中介绍了虚拟极化技术的原理及其在雷达接收中的应用。通过对微波暗室实测数据的分析和研究,得到了虚拟极化接收对目标信号的增强效果,并进一步分析了虚拟极化相对于同极化接收的增益情况,给出了相应的结论。Virtual polarization is an effective means to realize the adaptive adjustment of polarization in radar systems. In this pa- per, the principle and application of virtual polarization to radar receiving system are introduced. With real data obtained in the anechoic chamber, through analysises, the effect of virtual polarization for enhancing target signals is proved. Then the gain of vi- tual polarization receiving over co-polarization receiving is analysed, and corresponding conclusions are presented.
