Rotatable distributed radar life detection and positioning equipment

Abstract

The invention discloses rotatable distributed radar life detection and positioning equipment which comprises more than two independent radar units, each radar unit is provided with a rotating mechanism, and the independent radar units are enabled to rotate around a fixed shaft through the rotating mechanisms so as to adjust the polarization direction of an antenna. The equipment has the advantagesof simple structure, simple operation, wide application range, capability of realizing large-range quick search and full-polarization target 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 rotatable distributed radar life detection and positioning equipment. Background technique [0002] Radar life detection and positioning equipment is mainly used to detect survivors buried in ruins after earthquakes, landslides and other disasters. The general environment of the disaster site is harsh: mud, building ruins, steel bars and metal are all over the place; rescue site personnel and equipment are mixed, and all kinds of interference are serious. Most of the existing radar life equipment is single-base radar (that is, radar transmitters, receivers and other components are all packaged together as a complete device). Large-scale packaging, so the radar baseline is short, the angular resolution is poor, and it is difficult to perform multi-target detection. Secondly, after a disaster occurs, the affected area is generally large. Single-bas...

AI Technical Summary

Problems solved by technology

[0005] (1) Monostatic radar search is slow and positioning accuracy is poor;

[0006] Because the single-base radar can only detect a small-scale area near the location, it cannot detect in a large area at the same time, and the search speed is slow; the baseline of the single-base radar is limited by the outer box of the package, and it cannot perform large-scale baseline detection, and the angular resolution is poor, which eventually leads to Inaccurate targeting

[0007] (2) The situation of detection omission is serious;

The polarization direction of the existing radar is fixed, and targets inconsistent with the polarization direction of the radar will be missed in actual detection

[0009] (3) The wireless distributed radar is severely interfered;

However, in the complex environment of the disaster site, various personnel and equipment will seriously interfere with the radar wireless transmission channel, resulting in discontinuous data transmission and even equipment interruption; in addition, radar relies on transmitters to emit electromagnetic signals for detection, while WIFI wireless transmission data also uses electromagnetic waves In space transmission, this technology itself will also affect radar detection

Wireless networking devices will not work in places with weak GPS signals such as jungles and valleys

Therefore, the program is not very practical
