A novel method based on Monte Carlo simulation was presented for analysis of signal processing performance degeneration of linear frequency modulation (LFM) seeker radar in the radiation of high power microwave (HPM). The influence of HPM on the seeker radar was modeled as equivalent noise random process called equivalent noise process model. According to the signal processing of LFM radar, the radar signal processing performance figures, such as target radar echo integration efficiency, range resolution, velocity resolution and angle measuring precision etc, were theoretically analyzed under HPM radiation interference. The simulations reveal that serious performance degeneration was caused by the strength of equivalent noise process and the amplitude-phase's noise correlation.
Key words： seeker radar; high power microwave radiation; LFM; performance of seeker
