| 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. |
