摘　　要：鉴于雷达目标可等同于线性系统的概念 ,本文提出了雷达目标等效电路求取目标极点的思路。然后 ,针对导体球目标 ,求取了与几个低次模式波相对应的等效电路的复谐振频率。最后 ,对球体极点的理论值与等效电路的复谐振频率进行了比较 ,验证了方法的有效性 ,同时 ,进一步解释了雷达目标极点的物理意义。In this paper, a new technique is proposed for calculating the poles of the radar targets by means of equivalent circuit. Firstly, for the case of a perfectly conducting sphere, we have computed several complex resonance frequencies of it′s equivalent circuits. Secondly, we compare the complex resonance frequencies with the poles of the sphere. The result validates the feasibility of the method, and interprets the physical content of the poles of the radar targets.
