Abstract
A system and method using a multi-node radar system involve receiving reflected signals at each node of the multi-node radar system, the reflected signals resulting from reflection of transmitted signals by one or more objects, and generating velocity lines associated with each of the reflected signals received at each of the nodes, each velocity line being derived from a radial velocity Vr and an angle of arrival θ determined from the reflected signal received at the node. The method also includes determining one or more intersection points of the velocity lines, and estimating a velocity of each of the one or more objects based on the one or more intersection points. Each intersection point corresponds with the velocity for one of the one or more objects and the velocity is a relative velocity vector between the one of the one or more objects and the radar system.
