Figure 8: Signal processing workflow

Raw ADC Data (RADC)

– Samples ADC data from all 3 RX antennas

(1 Frame = 256 Samples x 256 Chirps)

Mean Range-Doppler (RMRD)

– Calculates the range-doppler map for all 3 RX antennas

– Averages the range-doppler map of all 3 RX antennas

Raw Target (PDAT)

– Find targets over threshold

– Range compensation

– Filtering with an exponential moving average

Tracking Target (TDAT)

– Uses an alpha-beta-gamma tracker to track targets

– Assigns objects to tracking channels

– Predicts temporary lost objects
