Converse beam cross sliding spotlight SAR (CBC sliding spotlight SAR) was recently proposed and researched. Unlike conventional sliding spotlight SAR, the CBC sliding spotlight SAR has the moving direction of its platform and ground beam center contrary to each other and in such mode, the azimuth scene extension is larger than that of a pure spotlight mode and the azimuth resolution of scatterers...
This is the first investigation on converse beam cross sliding spotlight SAR (CBC sliding spotlight SAR) which was firstly proposed in this essay. In conventional sliding spotlight SAR, the azimuth scene extension is larger than that of a pure spotlight mode and the azimuth resolution of scatterers is higher than in classical stripmap mode. The geometry and properties of classical standard and inverse...
Different properties of two operation modes for cruise missile borne side looking instantaneous imaging synthetic aperture radar with linear array antenna along flight track were investigated. Its theoretical azimuth resolution was induced and a novel imaging algorithm called compound range-doppler algorithm was proposed. The imaging procedure was given and images were gained with both ECS and compound...
The principle of one kind of digital beam forming SAR called single phase center multiple receiving beam synthetic aperture radar (SPC-MB SAR) was analyzed and imaging simulations were executed in this essay. The imaging algorithm was detailed investigated and the processing diagram was given. All simulation results proved that the algorithm is correct and can be greatly used in single phase center...
Study of frequency coded synthetic aperture radar was concerned in this paper. A new frequency-domain extracted IFFT approach (FDE-IFFT) to obtain high range resolution profile was proposed, and the mathematical principle of this new method was detailed analyzed. Simulation results and series of radar images using time domain back-projection method were given in the end. All results proved that the...
