Abstract :
Improving azimuth resolution is the main problem for forward looking Synthetic Aperture Radar (SAR). Aiming at forward looking SAR with receiving array, the azimuth signal is modeled as the sum of exponents firstly. Then a super-resolution algorithm based on state-space model (SSM) is present for improving azimuth resolution. Finally, simulation result proves the validity of the algorithm.
