The detection methods for locating the electromagnetic leakage position on the surface of microwave equipment are researched.According to the different style of the equivalent radiation source

several different detection methods are designed

and the corresponding experimental test plans are also presented.Among them

the synthetic aperture passive radiometer imaging method is suitable for the situation that the equivalent radiation source is incoherent;the digital lens imaging method is suitable for the situation that the equivalent radiation source is coherent;the physical lens imaging method is suitable for all the three situations that the equivalent radiation sources are incoherent

coherent and partial coherent.
