| 摘 要： | 分析了Chirp雷达系统中包络走动对积累检测的影响,然后提出了两种有效的积累算法:时移包络补偿积累算法和包络插值移位补偿积累算法,分析了其原理、步骤及运算量。仿真结果显示后者的性能要优于前者。这两种方法在低信噪比条件下都能够实现较长时间的有效积累。

| Abstract: | The influence of envelope migration to the integration in Chirp radar system is analyzed,and two effective integration methods are presented.The principles,steps and operation amount of the two methods are introduced in detail.Simulation results indicate that the performance of the integration with interpolation and migration compensation is better than that of the integration with moving the envelope in time domain.The two methods can all achieve relatively longtime effective integration when the input SNR is very low. |
