A signal processing pipeline was developed to generate spectrograms, isolate the ball’s return signal and estimate its peak velocity. Experimental testing was conducted in a controlled indoor environment, with ground truth ball speeds obtained through video analysis for validation. The IPM-365 produced clearer spectrograms and demonstrated more consistent performance for short-range measurements, with radar-based speed estimates deviating less than 10% from the video-based values. This study investigates the comparison between these radar modules for soccer applications, highlighting the IPM-365’s potential for low-cost, accurate ball speed measurements in amateur sports settings.AbstractenContinuous-wave radarCW radarIPM-365uRADSoccer ball speed estimationSpectrogram analysisAmateur sports applicationsConference Presentationn/a
