A simple method for estimating the velocity based on the Doppler shift
A simple method for estimating the velocity of a moving target is presented, based on the Doppler shift. The relationship between the ML estimation and the FFT is exploited to obtain a practical implementation. With the help of adaptive noise canceling to increase the input SNR of the FFT, high-precision analysis for the single-frequency signal is easily accomplished. Simulation shows that the method presented meets the high demand required in practice.
