1. A collision avoidance system for an unmanned vehicle, comprising:
- a plurality of transmitter elements;
a plurality of receiver elements for receiving a plurality of return signals from one or more objects within range of said unmanned vehicle; and
at least one processor coupled to the transmitter and receiver elements, said processor being adapted to;
transmit form said plurality of transmitters a set of pulses about the unmanned vehicle;
generate from said return signals a plurality of conical beams covering a volume of interest about the vehicle;
analyze one or more signals within the plurality of conical beams to determine if one or more objects within range of the unmanned vehicle are on a collision path; and
alter the course of the unmanned vehicle upon determining that at least one object of the one or more objects is on a collision path with said unmanned vehicle.

Abstract
A collision avoidance system for use with an unmanned vehicle, the system includes a plurality of radar elements arranged parallel to the longitudinal axis of the unmanned vehicle, wherein the radar elements transmit a plurality of pulses about the vehicle and receive a plurality of return signals from one or more objects within the range of the vehicle. Upon detecting the one or more objects within range of the vehicle, the system determines if an object is on a course which requires evasive action and suitably alters the vehicle'"'"'s course in order to avoid collision.
