| Abstract: | By analyzing terminal flight of cruise missile,the geometric distortion under high squint SAR and scene mismatching were studied.Based on the extended chirp scaling algorithm,a novel range scaling formulation was proposed for geometric correction processing of high squint data and scene matching of terminal guidance.The simulation result shows the superiority of the proposed algorithm compared with the traditional CS algorithm. |
