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