摘　　要：首先介绍了电大目标回波信号极化特征和电子假目标信号极化特征,接着探讨了理论上雷达根据极化信息区分电子假目标信号和真实目标回波信号的方法,分析了实际应用中可能存在的困难,说明了这种方法在目前和今后雷达目标识别技术发展中是有实际意义的。最后说明了无论是现在,还是今后,极化信息对于雷达目标识别来说都是一个极其重要的参数。Firstly, the polarization characters of the electrically large size objects＇ radar echo signal and the electronic spurious target signal are introduced, and then a theoretical method is proposed for radar to differentiate electronic spurious target signal from real target echo signal according to the difference of their polarization domain. Though this method may meet much difficulty in practice nowadays, it will be useful in developing future radar target recognition technology. Lastly, the polarization information is a very useful parameter for radar to recognize target whether today or in future.
