Abstract

Aiming at the requirement of the range and azimuth resolution of the near range target detection system, this paper completed the design of wideband real-time SAR imaging system. The system adopts “FPGA+RFADC+RFDAC” architecture, it can timely generate LFM(Linear frequency modulation) signal in L/S frequency band , complete the preprocessing of radar echo signals and realize the real-time SAR imaging algorithm, finally upload the imaging results in real time. The effectiveness of each function of the system is verified by simulation and actual measurement.
