Detector

The detector identifies significant peaks in the Range-Doppler domain by evaluating FFT magnitudes

against predefined or adaptive thresholds, and outputs peak indices and corresponding signal strength for further processing.

1. Peak Detector

A peak detector identifies local maxima in the Range or Range-Doppler domain by comparing signal amplitudes against neighboring bins or a fixed threshold.

It is computationally simple and low-power, making it suitable for low-cost radar SoCs, but its detection performance is sensitive to noise and interference.

3. CFAR Detector

A CFAR detector adaptively sets detection thresholds based on the estimated noise floor from surrounding reference cells in the Range or Range-Doppler map.

It provides robust target detection under varying noise and clutter conditions at the cost of higher computational complexity compared to simple peak detection
