Telescopic distributed radar life detection and positioning equipment

Abstract

The invention discloses telescopic distributed radar life detection and positioning equipment which comprises more than two radar units, the two adjacent radar units are connected through a telescopicmechanism, and the telescopic mechanism is used for increasing or decreasing the distance between the two adjacent radar units. The equipment has the advantages of being simple in structure, easy andconvenient to operate, wide in application range, capable of achieving multi-mode detection and the like.

Description

technical field [0001] The invention mainly relates to the technical field of radar life detection equipment, in particular to a scalable distributed radar life detection and positioning equipment. Background technique [0002] Radar life detection and positioning equipment is mainly used to detect people buried in soil and ruins after earthquakes, landslides and other disasters. Generally, the radar is packaged in a three-proof box. Considering the actual application scenario, the equipment must be small and portable, so this type of product The overall size is relatively small. Since the radar is packaged in a relatively small box as a whole, the transceiver antenna cannot be deployed, the radar baseline cannot be stretched, the angular resolution is poor, and the positioning is not accurate. [0003] Since the existing single-base radar life detector is packaged in a box as a whole, the transmitting antenna and the receiving antenna are facing the same direction during d...

AI Technical Summary

Problems solved by technology

This solution has the following problems: WIFI data transmission will be affected by environmental electromagnetics, data packet loss and disconnection problems will occur, and WIFI signals and radar detection electromagnetic signals interfere with each other, resulting in a decrease in detection performance; GPS timing in forests, canyons or buildings There is no signal inside, and the radar cannot be timed, which makes the radar unable to work; this solution needs to add WIFI module, GPS module, GPS antenna and other components, which increases the cost of equipment, and also makes the system complex and heavy, and cannot be portable

[0007] 1) The existing single-base radar life detection equipment has a short baseline, resulting in poor resolution and inaccurate positioning

[0008] 2) The radar detection polarization direction is single, it is difficult to detect various posture targets buried in the ruins, and the false positive rate is high

[0009] 3) Existing monostatic radars can only perform one-dimensional or two-dimensional positioning, and cannot achieve three-dimensional positioning

[0010] 4) When using wireless distributed radar network detection, the data transmission between each radar unit is unstable, and the WIFI transmission data will affect the normal detection performance of the radar
