Abstract :
This paper introduces a method to combine a number of narrow-bandwidth chirp pulses stepped in frequency in order to achieve high range resolution in SAR images. The limitations of this method are discussed, as well as some of the design constraints appropriate to designing a high-resolution stepped-frequency SAR system. Results obtained from processing simulated and E-SAR data are presented and discussed
