Abstract :
The utilization of a Linear Frequency Modulated Continuous Wave (LFM-CW) signal with Synthetic Aperture Radar (SAR) systems provides the possibility to obtain a small, low-cost and high resolution imaging radar. In this paper, a strip-map mode of LFM-CW broadside SAR is considered at X-band. The Range-Migration Algorithm (RMA) for processing LFM-CW SAR is investigated and analytically developed. The simulation results indicate the resolution improvement introduced with RMA; and also emphasize the effects of different parameters such as RF bandwidth and size of an antenna in cross-range direction on the performance of LFM-CW SAR system.
