Abstract :
This paper mainly introduces a high-performance system of real-time Ultra Wide-Band (UWB) SAR processing. Firstly, the sub-aperture Nonlinear Chirp Scaling (NCS) algorithm is optimized and selected to form the UWB SAR image, and then it is mapped to the Multiple Digital Signal Processor (Multi-DSP) board. Secondly, the timing sequence of the realtime processing is analyzed, and the processing time of each task is measured. Finally, the simulation result of the realtime UWB SAR processing is given.
