Abstract
A radar monitoring system and a radar monitoring method for monitoring a traffic control zone involve installing two radars near the traffic control zone so that the radars emit radar waves covering the traffic control zone and serve as backups for each other; locating any object in the traffic control zone as a coordinate point with respect to a set of X and Y coordinate axes, and subjecting the X and Y coordinate axes of the two radars to axial normalization, so that an identical object in the traffic control zone is located by the first radar and the second radar at approximately the same coordinate point. An alert area is defined in the traffic control zone and an excluded area around a resident facility in the traffic control zone is excluded from the alert area. When an object in the alert area is determined as an obstacle, an alert is triggered.
