Abstract

As limited by the size and load, multi-array antenna can not be installed in the helicopters to achieve forward-looking SAR imaging. A "bistatic" forward-looking imaging program is proposed, which used a satellite to carry illuminator and a helicopter to carry receiver. Then the forward-looking SAR geometry model and echo signal model are built. At last, the Doppler features are deeply analyzed, especially the variation of the Doppler frequency center, Doppler frequency rate and Doppler frequency third term when depression angle and receiver altitude change. The results provide a theoretical support for forward-looking SAR imaging algorithm and azimuth resolution research.
