Abstract	A CW Doppler radar can measure radial velocity by acquiring Doppler frequency shift proportional to the speed of moving object. To acquire Doppler frequency shift, FFT (Fast Fourier Transform) method is conducted. It is used for the transformation of time domain signal to frequency domain data. A time and radial velocity resolution can be determined by sampling frequency and number of FFT which is used for acquiring velocity data. A number of FFT can be constrained by acceleration and sample frequency is constrained by maximum target velocity. So in this paper, not only the sample frequency effect on time and radial velocity resolution, but also effect on the SNR(Signal to Noise Ratio) to increase measurement accuracy and range performance is described.
