Paper Abstract

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 briefly described. Sets of the simulation results are then given as demonstrations to show its effectivity.
