A novel millimeter wave synthetic aperture radiometer passive imaging system

A novel millimeter wave (MMW) passive imaging system scheme is introduced in this paper. By combining two technologies, namely one dimension synthetic aperture interferometer radiometer (SAIR) and real aperture with electronic scan beam in another dimension, this MMW passive imaging technology meets the demands such as high space resolution, high sensitivity, large instant field of view (FOV), low cost and light weight. The system principle as well as performances of signal detection is analyzed. Typical Ka band system design and system simulation results are given.
