单脉冲精密测量雷达主要用于火箭发射及太空运动目标的轨道测量,背景杂波和同频干扰是制约单脉冲雷达准确捕获目标的关键因素。文中利用小波变换结合距离引导值的方法实现该雷达的回波信号去噪,有效地解决了单脉冲雷达在低信噪比和同频干扰存在的两种情况下的降噪问题,提高了雷达的抗干扰能力,并通过仿真给出了去噪的结果。

Single pulse precision measurement radar is mainly used for orbit measurement of rocket launch and space moving target. Background clutter and same frequency interference are the key factors that restrict the accurate capture of single pulse radar. In this paper, the echo signal de-noising of the radar is realized by means of wavelet transform combined with the distance guidance value, which effectively solves the noise reduction problem of the single pulse radar in the two cases where the low signal-to-noise ratio and the same frequency interference exist, and improves the anti-jamming ability of the radar. The result of de-noising is given by simulation.
