To systematic study the effect of high power microwave radiation on the overall performance of the radar-guided indexes, the effect of phase noise on the front amplifier of radar receiver was analyzed. With the MATLAB, a radar signal model and a computer simulation method of phase noise under the high power microwave radiation were given. Combined with the pulse compression and pulse Doppler processing of Barker PD radar, the effect of phase noise on the front of Barker PD radar guidance in signal processing and target detecting was studied. At last, the qualitative and quantitative relationship between the signal and information processing performance of Barker PD radar and strength and relevance of phase noise with the typical parameters was given.
