A method includes an operation to collect radar signals reflected from objects in a field of view. Range-angle-doppler bins representing three-dimensional objects in the field of view are formed. A local median operation is used across a selected dimension of the range-angle-doppler bins to eliminate background noise in the range-angle-doppler bins. Low energy peak regions are masked by removing radial velocity values in the selected dimension to form a sparse range-angle two-dimensional grid. The radar signals reflected from objects in the view of view are processed to extract reflection point detections. Reflection point detections are tracked in accordance with short-term filter rules to form tracked reflection point detections. The tracked reflection point detections are formed into clusters. The clusters are processed with long-term filter rules.
