摘　　要：非相参积累技术是雷达信号处理中提高回波信号信噪比的重要方法。非相参积累是对目标反射回的回波信号进行的积累,目标的状态影响着回波信号的形式,运动目标造成了回波信号的起伏变化,起伏目标下的非相参积累显得尤为重要。对起伏目标下的非相参积累与信噪比的关系进行了详细分析,通过数据对不同起伏目标下非相参积累的检测性能进行了仿真比较,并通过对比的结果得到了一些结论。The technology of noncoherent integration is an important method in radar signal processing, it could improve the SNR（Signal to Noise Ratio） of the return signal. Noncoherent integration is the integration of the return signal reflected back from the targets, the targets＇ state affects the form of the return signal. The moving targets cause the fluctuating of the return signal, so noncoherent integration under the fluctuating targets is particularly important. It analyzes detailedly the relationship between noncoherent integration under the fluctuating targets and the SNR, simulates and compares the detection performance of noncoherent integration under the different fluctuating targets through the data, and gets some conclusions through the result of constrast.
