Multi-mode self-positioning networking radar life detection method and device

Abstract

The invention discloses a multi-mode self-positioning networking radar life detection method and a multi-mode self-positioning networking radar life detection device. The method includes the steps: more than two radar life detection components are assembled into a life detection network; each radar life detection component determines a self position through a positioning system; each radar life detection component determines the position of a to-be-detected life body on a self-radar-echo by emitting and receiving an ultra wide band pulse signal; a one-dimensional (1D) multi-target detection way, a three-dimensional (3D) high-precision detection way, a detection way combining the two ways are adopted to conduct target detection to obtain a coordinate of the to-be-tested radar life body. The device comprises a satellite difference positioning unit, a detection control and display system, and more than two sets of radar life detection units, wherein the more than two sets of radar life detection units form the life detection network. The method and the device have the advantages of being convenient to operate, superior in performance, high in positioning precision, capable of improving efficiency of searching and rescuing victims and the like.

Description

Technical field [0001] The invention mainly relates to the field of life search and rescue equipment, and particularly refers to a method and device for life detection of a multi-mode self-positioning networked radar. Background technique [0002] Natural disasters have the characteristics of instantaneous occurrence, severe damage, difficulty in monitoring and forecasting, and profound social impact. For example, devastating earthquakes, landslides and other disasters have caused huge damages and losses to the country’s economic construction and people’s property safety. Numerous examples of natural disasters at home and abroad have proved that the technical level of emergency rescue after disasters is extremely important for reducing disaster losses. [0003] At present, domestic disaster emergency rescue technology is still very weak, mainly relying on manpower, search and rescue dogs, and conventional life detection devices for life detection to find survivors. However, the d...

AI Technical Summary

Problems solved by technology

However, the detection efficiency of the above-mentioned conventional search and rescue methods such as manpower and search and rescue dogs is relatively low, and it is greatly affected by the surrounding environment, which cannot meet the needs of timely and rapid

Existing ordinary life detection devices have shortcomings such as small search space, slow search speed, and lack of 3D positioning capabilities, which are far from meeting the actual needs of large-scale and rapid search and rescue of trapped people buried in post-disaster ruins
