Abstract
An active scanning collision avoidance system for vehicles and the like. In one embodiment, an active scanning radar module is affixed to a vehicle's roof. A microwave transmitter sends out a signal to a directional antenna or array directed outwards radially away from the radar assembly. When this transmitted signal is reflected off another vehicle or object, it is received by a second directional antenna or array. This return signal is mixed internally with the transmitted signal, and the resulting signal is amplified and processed so that distance, velocity and object size can be determined. These object attributes are transmitted to an in-vehicle display in real time for quick and informed decision-making for the driver.
