Abstract :
The paper describes a novel approach combining space filtering with bandwidth synthesis to achieve wide swath and high range resolution, Firstly, Low PRF is adopted to achieve unambiguous wide swath; then space filters is used to remove azimuth ambiguity; finally sub-band signals are combined into a wider band signal to achieve high range resolution. Simulation results are provided to show the validity of the proposed method.
