%X The CLEAN algorithm is introduced from non-instant u-v coverage aperture synthesis in radio astronomy to instant situation in 2-D airborne mm-wave imaging, to remove the bad influences of the undersampled u-v plane coverage to image quality so as to eliminate the negative impacts on the image caused by high side slobs. In this paper, the effects of the kind of “clean” impulse, the relevant FWHM and the scale coefficient γ to the quality of the modified image is mainly studied, and a conclusion is that: a Gauss “clean” impulse, a relevant FWHM equal to the FWHM of system response and the scale coefficient γ about 1/256 is favorable to improve the modified image. This conclusion is valuable to the real airborne mm-wave aperture synthesis imaging project.
