A subaperture imaging approach of spaceborne spotlight SAR
摘要
Signal properties of spaceborne spotlight SAR. arc; discussed. Based on the analyses of a few .spotlight imaging algorithm, a modified chirp scaling algorithm for spaceborne spotlight SAR is proposed. Besides, a subaperture method is combined with the algorithm. In order to resolve high Pulse Repetition Frequency (PR.F) and the time-variant of Doppler center frequency, etc., the necessity and implementation approach of the subaperture method are analyzed thoroughly. The validity of the proposed method is tested by computer simulation.
