An Improved Subaperture Algorithm for Airborne SAR Imaging Under Arbitrary Aircraft Maneuvers
In airborne synthetic aperture radar (SAR), the arbitrary aircraft maneuvers significantly degrade the achievable performance of the imaging system. Compared with other SAR processing algorithms, the time-domain subaperture processing is tested to be more effective in handling the problems, where the real-time adjustment of the radar parameters is required. In this paper, a subaperture image formation for high-quality SAR imaging without changing any parameters is presented. Some new characters are first described in detail. Sets of the simulation results are then given as demonstrations to show its effectivity.
