Abstract
A method of detecting a moving target within a predefined protected region with a microwave motion detector, by transmitting microwave frequency signals and receiving the microwave frequency signals reflected by a target. A target distance is then determined from the received microwave frequency signals, and a target angle is determined from the received microwave frequency signals. Then, a target location is determined from the target distance and the target angle, and an alarm condition is set if the target location is within the predefined protected region.
