摘　　要：连续波雷达存在发射信号泄露的现象,泄露的发射信号边带噪声会淹没目标回波信号,使接收机灵敏度降低。而传统连续波雷达方程并没有考虑到这一现象对雷达性能的影响。在分析了传统连续波雷达方程的不足后,通过增加收发通道隔离度和发射信号相位噪声两个参数,对传统连续波雷达方程进行修正,使雷达方程中体现了发射信号泄露对连续波雷达的影响。这种改进的连续波雷达方程可以更切实际地描述出作用距离和雷达参数及目标特性之间的关系。The continuous wave （CW） radar has the age of the transmitted signal sideband noise would drown phenomenon of transmitted signal leakage. The leak the echo signal of targets and lower the receiver sensi tivity. The traditional CW radar equation does not consider the effect on the performance of radar. By increasing the two parameters of the transmitter receiver isolation and the phase noise of the transmitted signal, the traditional CW radar equation is modified after analyzing its deficiency. The influence of transmitted signal leakage on the CW radar is reflected in this radar equation. This improved CW radar equation can be more realistic to describe the relationship between the range and the radar parameters and the target characteristics.
