SOJ干扰下目标检测概率降低，容易出现检测不到目标真实回波，如果此时再施放RGPO干扰，由于RGPO回波比目标回波幅度强，雷达更容易误将RGPO干扰回波当成真实目标的回波。针对上述特点，提出了采用检测门限自适应与卡方检验相结合的方法实现了对RGPO的鉴别，同时采用多假设跟踪实现了此种复合干扰下的目标跟踪方法。仿真实验表明，此方法具有较高的RGPO鉴别概率同时也可以较好地实现干扰下目标的跟踪，具有一定的实际工程意义。

In the presence of SOJ,the target’s probability of detection decreases and the echo of target can’t be detected. If RGPO is used simultaneously,the echo of RGPO will be detected as target wrongly,because the SNR of RGPO is higher than the skin return. Aimed at these problems,the paper presents a method based on adaptive detection threshold selection and Chi-square test to discriminate RGPO. And the target is tracked by MHT algorithm. The simulation results show that the algorithm presented in this paper can increase the probability of RGPO discriminating and has a good performance on anti-jamming and also a significance in practical application.
