摘要: 本文提出采用软件无线电技术实现某型脉冲多普勒雷达导引头目标回波模拟器的校准。使用频谱仪及示波器组成校准装置实现被校信号射频到中频的变换及A/D转换,使用LabVIEW软件实现A/D转换后信号的数字正交解调及参数提取算法,进而实现雷达导引头目标模拟器的脉冲幅度、多普勒频率及延时参数的自动校准。

关键词: 回波, 多普勒频率, 延时, 正交解调

Abstract: The calibration method of the target echo simulator for pulse doppler radar seeker based on software radio is prposed in this paper. The conversion of a calibrated RF signal to an IF signal and A/D conversion of the IF signal is realized by using spectrum analyzer and oscilloscope which formed the calibration device. The digital quadration demodulation and parameter extraction algorithm of the signal after A/D conversion is achieved by means of LabVIEW and then automatic calibration of the pulse amplitude,doppler frequency and delay parameters of the target echo simulator for radar seeker.
