Abstract

A radar sensor system comprises a first radar sensor and at least a second radar sensor and one or more processors configured to assign different pulse rate intervals (PRI) to the first radar sensor and the second radar sensor. The processor(s) s are further configured to: receive ambiguous velocity estimates from the first and second radar sensors, respectively; determine maximum detectable velocity (Vmax) values for the first and second radar sensors based on their respective PRIs; generate a first velocity vector for the first radar sensor based on the first Vmax and the first ambiguous velocity estimate; generate a second velocity vector for the second radar sensor based on the second Vmax and the second ambiguous velocity estimate; compare velocity values in the first and second velocity vectors; and identify and output a velocity value common to the first and second velocity vectors as a correct unambiguous velocity of the object.
