Abstract: A method comprises transmitting a radar signal into an target area, receiving reflected portions of the radar signal from the target area, and processing the reflected portions of the radar signal. The step of processing comprises windowing analog signals representative of the reflected portions of the radar signal, performing a fast Fourier transform on the windowed analog signals to produce an FFT result for each window, and obtaining the average of the FFT results from consecutive windows. In accordance with the method, a user receives indication from an indicator that a golf ball is present in the target area when the average of the FFT results corresponds to characteristics of the golf ball. The system comprises a radar transceiver, a processor for processing reflected portions of the radar signal, and an indicator indicating to the user a golf ball present in the target area.
