The microwave radiation signal is a “noise-like ” stochastic signal, and the SAR image has random characteristics. The statistical distribution model of synthetic aperture radiometer (IFAR) is deduced, and the calculation method of target detection probability based on synthetic aperture radiometer (IFAR) retrieval image is proposed. The maximum detection distance equation of synthetic aperture radiometer is given. Taking the 100-unit T-type antenna array as an example, the performance of the synthetic aperture radiometer for air stealth target detection is analyzed. The experiment is verified by simulation. The results of the dissertation will provide the theoretical basis for the application of synthetic aperture radiometer technology in stealthy target detection.
