DOPPLER RADAR WARNING SYSTEM

摘要

A Doppler radar warning system (30) adapted for use as an automotive safety system including Doppler radar transceiver (31), a digital signal processor (55) for receiving the Doppler radar signals, resolving the signals into a phase difference and determining the distance between a target (42) and the receiving antenna (44), as well as the relative speed of the target (42), and displaying the distance and rate of speed information on a visual (64) and/or audio display (66), including its application in an integrated vehicle and/or building safety warning system including a camera and Doppler radar unit to provide sensing in a surveillance zone of three-dimensional features of objects located in the zone, range information regarding objects located in the surveillance zone, and rate of speed of motion of objects within the surveillance zone.
