Abstract

Doppler radar real-time signal processing is one of the core equipment in the speed measuring system. The working principle is presented in this paper, and an efficient real sequence FFT algorithm is proposed based on the Fast Fourier Transform, which can reduce the computation complexity effectively. The design with low cost FPGA implementation, high performance, high flexibility, speed and other characteristic feature, and through the engineering application proves that the design is correct and feasible.
