| 摘 要： | 传统的单脉冲跟踪雷达在测速时采用FFT实现动目标检测模块,由于频率分辨率相对较低,使得存在相对较大的测速误差.文中在FFF基础上,运用高低通滤波器原理,采用精确计算得出多普勒频率偏差的方法,从而提高了频率、目标速度的测量精度.计算机仿真和外场试验结果均表明了此方法的有效性.目前该方法已应用于某单脉冲跟踪雷达系统.

| Abstract: | The traditional monopulse radar uses FFT in tracking speed to realize the moving target detection module.This method may lead to a relatively large Doppler error because of the low frequency resolution.This paper proposes a Doppler frequency deviation method using the principle of low and high filter and the method of accurate calculation,which significantly increases frequency resolution and improves speed measuring precision.The computer simulation results and the field test results indicate that this met... |
