Abstract

Abstract: A quick look imaging formation method (QLFM) and its realization for the existing airborne stripmap SAR system are put forward in this paper. After the De Chirp operation on echo returns along both the azimuth and slant range direction, a two dimensional inverse Fourier transform is carried out to form the output imaging directly. Computer simulation and raw data imaging results are used to verify the feasibility of this quick look method in airborne SAR systems.

Key words: synthetic aper ture r adar, quick look, De-Chir p
