Urban RF multipath mitigation

Sensing in urban environments is of growing interest to the surveillance community, as is observation of targets with micro-Doppler features - elements of the target structure with independent range-Doppler behaviour about some target centroid. Multipath effects unique in character to urban sensing can conceal important features in the range-Doppler response of a target with micro-Doppler behaviour. The range-Doppler smearing because of multipath is analysed, and this analysis serves as the basis for a prominent point multipath mitigation algorithm. The effectiveness of this technique is evaluated with simulated micro-Doppler data with artificial multipath effects.
