Abstract :
A prototype of 8mm band two dimensional Intererometric Synthetic Aperture Radiometer (InSARad) has been developed in the Electromagnetics Laboratory of BeiHang University. It consists of a Y-shaped antenna array with 24 antenna/receiver elements, a FPGA based 1bit/2levels digital cross-correlation unit and a data processing subsystem. The primary testing and imaging experiments have been carried out, and the initial results are encouraging. The instrument overview, calibration method, and preliminary imaging results are presented in this paper.
