| Abstract: | In this paper, the principle of improving the range resolution of Synthetic Aperture Radar (SAR) using Linear Frequency Modulated (LFM)burst pulses is introduced. Then the signal processing arithmetic and steps of LFM burst pulses SAR is suggested. It can avoid widening bandwidth of radar system for high range resolution. The validity of the arithmetic is tested through simulation and the calculation overhead is analyzed. In the end, the design of the corresponding real-time signal processor is presented. It satisfies the request of the new mode SAR system with high speed image processing. |
