Abstract

The Compressive Reflector Antenna (CRA) has the ability to span dynamic pseudo-random phase wave-front in space, which can be used to modulate the echo in phase, replacing the traditional Doppler style. That means radiometric observing imaging have the opportunity to be implemented in geostationary orbit, a kind of special geosynchronous orbit. For the extremely low SNR in this geometry, we propose using matched filter to improve the SNR and make the constructing more precision. In imaging aspect, we use the Back Projection and Compressed Sensing techniques to imaging at each range gate. Resampling operation is applied to eliminate the influence from the matched filtering. And some necessary simulations have been done to verify the rationality of observing system and imaging algorithm.
