针对采用恒虚警检测的线性调频脉冲压缩雷达，提出多假目标联合灵巧噪声的协同压制干扰方法。首先阐述了利用卷积调制转发实现多假目标压制干扰的机理，并推导得到压制信号关键参数值，如假目标个数及干噪比。然后分析了多假目标干扰在侦测参数存在误差时的不足之处，并进一步计算进行协同干扰所需的压制噪声功率。最后对协同压制干扰的效果进行了仿真验证，仿真结果表明，该方法能够降低目标发现概率，实现对雷达检测环节的有效干扰。

A cooperative suppress jamming method uniting multi-false-target and smart noise for the linear frequency modulation pulsed radar with the mean level constant false alarm ratio detector is proposed.Firstly, the proposed method is illuminated about how it takes advantage of the convolution modulation to realize the dis-tribution of multiple false targets.After that several key parameters such as the number of the false targets and the signal-noise ratio are derived.Due to the poor performance of the multiple false targets under the condition of deviations exist in measured values,noise jamming is proposed to promote the effect of cooperative jamming, and then the required power of noise is calculated.Finally,simulations are made to validate the effect.Simula-tion results show that the cooperative jamming can reduce the detection probability of radars greatly and the de-tector of the radar is jammed effectively.
