Through-the-wall radar human body detecting device

Abstract

The invention discloses a through-the-wall radar human body detecting device. The through-the-wall radar human body detecting device comprises a cabinet, a transmitting antenna and a receiving antenna; the front of the cabinet is provided with a control display panel; the right side portion of the cabinet is provided with the transmitting antenna and the receiving antenna; the transmitting antenna and the receiving antenna are arranged at a medium plate roof of the cabinet; the transmitting antenna and the receiving antenna are both set as ultra wideband antennas; the receiving antenna comprises a metal antenna arm 1, a loading resistor 1, a loading resistor 2, an impedance transformer and a radio frequency coaxial connector; and the metal antenna arm 1 and the metal antenna arm 2 are both printed on the bottom surface of the medium plate roof through a printed circuit board printing technology, so that a planar ultra wideband dipole antenna can be formed. The through-the-wall radar human body detecting device of the invention has the advantages of advanced design as well as being safe, stable and reliable, and greatly improve the overall performance of through-the-wall radar human body detection. The ultra wideband antennas have the advantages of wide working broadband and excellent time-domain characteristics, and can meet requirements of a system for detection distance and accuracy.

Description

technical field [0001] The invention relates to a radar detection device, in particular to a through-wall radar human body detection device. Background technique [0002] When countering terrorism and rescuing hostages, operators often need to know the position and movement status of people in the building. Compared with infrared detectors, X-ray detectors, ultrasonic detectors and other sensors, radar has better penetrating ability and Not easily affected by practical factors such as weather, temperature, humidity, etc., through-wall radar human body detection and tracking technology has broad prospects in both military and civilian products. Studies have shown that continuous wave radar can detect the breathing and heartbeat of the human body behind the wall, but continuous wave radar can only give the frequency domain information of the target, and has high requirements for the detection environment and is easily interfered. From the perspective of long-term technological...
