FPGA implementation of UWB radar signal processing for automotive application

A radar signal processor of 24GHz UWB pulse radar for automotive short-range application is presented. A FPGA-based architecture for this signal processor is proposed to fulfil the real-time system requirement. The high performance of the proposed architecture was feasible since the employment of parallel hardware processing modules, like a 64-point FFT, a CFAR processor, and other extra processing modules. Also our signal processor supports the external DDR2 memory in order to speed up the data transfer between the signal processor and a memory. Also in this work, our radar system was simulated as our radar working scenarios using the variable pulse length and the phase modulation. Experimental results of the FPGA implementation are presented.
