Abstract

The invention discloses a circumference security radar system. The system comprises a first radar module, at least one second radar module, at least one third radar module, multiple infrared detectionsensors and master control equipment; the first radar module comprises a first signal emission unit, a first signal receiving unit and a signal reflector; the first signal emission unit and the firstsignal receiving unit and the radar reflector are arranged at two ends of to-be-monitored circumference, wherein the first signal emission unit and the first signal receiving unit are located at thesame end, and the radar reflector is located at the other opposite end; the first signal emission unit emits first microwave energy to the to-be-monitored circumference, the first microwave energy isreflected to the first signal receiving unit through the signal reflector, the first signal receiving unit judges whether the circumference through behavior is existent by monitoring the first microwave energy; and the second radar module comprises a first microwave emission unit and a first microwave receiving unit. Through the circumference security radar system provided by the invention, the sensitivity and accuracy of the detection can be improved, and the dead angle detection is avoided.

Description

technical field [0001] The invention belongs to the technical field of safety monitoring equipment, and in particular relates to a perimeter security radar system. Background technique [0002] At present, there are two perimeter protection technologies based on electromagnetic waves: one is perimeter security radar based on Doppler measurement; the other is microwave directing. Traditional perimeter security radar generally adopts the Doppler system. When the target has a radial motion component relative to the radar, the target echo has Doppler modulation. The radar detects the target by distinguishing the Doppler difference between the target and the ground background. Microwave cross-radiation consists of a transmitter and a receiver. There is a microwave energy field between the transmitter and the receiver. When the energy field is blocked, the microwave energy received by the receiver changes, so that the crossing behavior can be detected. [0003] Perimeter security...
