Abstract:

This paper presents a method for processing stripmap SAR data by using spotlight imaging algorithms. This method is based on dechirp demodulation and different characters of input data of stripmap and spotlight IFP. A frequency unfolding approach is also used. Spotlight data can be simulated by using this approach, and spotlight imaging algorithms can be studied when spotlight data aren't accessible. Furthermore, this approach can also be used in super resolution and quick look imaging formation.
