摘　　要：结合所设计的自适应极化捷变雷达系统原理框图 ,根据实验分析了自适应极化系统抗极化干扰的工作原理 ,评估了该系统抗极化干扰的得益。所得结论与实验结果吻合。给出的自适应极化捷变系统的工作原理简洁 ,简化了技术措施 ,对于单干扰和多干扰均有 30dB得益 ,这一重要战术指标远优于其它抗干扰措施 ,表明了发展极化雷达的重要意义。On the basis of our experimental study and with reference to the design principle diagram, this paper analyzes the operation principle and the antijamming effect for the quadrature channel adaptive polarization system. The results obtained are coincident with the experiment results. The operation principles are simple and the technical measures are advanced in the given system. There is a 30dB gain in this system under single jamming and multiple jamming. This important tactical index is far superier to that of the other antijamming measure, which indicates the great significance of developing polarization radar in the world.
