Paper Abstract

The detector array of THz synthetic aperture imaging system is consists of many individual detectors. At a specific distance, arranging the curvature of the detector array to match with wavefront can reduce the phase shift. There is not exist perfect detected object in reality. Given the specification resolution of a system, cut-off frequency is determined to design the longest baseline and to ensure an efficient coverage of the u-v plane. The shorter of the baseline, the more influence on u-v spectrum is. To be pointed out, throwing away the high frequency component can improve the resolution of the object. In this paper, by arranging the detector array to make the curvature of imaging array match with the wavefront and to throw away the high frequency component when the baselines are lost, the result of research proves the above way is right.
