Abstract

The invention discloses a life detection device and a detection method carried by an unmanned aerial vehicle, wherein the detection device includes a sky-side detection radar device and a ground-side display control device, and the sky-side detection radar device includes an antenna, a radio frequency module and a baseband processing module; a radio frequency module Including digital frequency synthesizers or phase-locked loops, power amplifiers, circulators, low-noise amplifiers, combiners, mixers, band-pass filters, gain-controlled amplifiers, limiters, analog-to-digital converters, and antennas, digital Frequency synthesizer or phase-locked loop, power amplifier, circulator and antenna constitute the transmission channel; antenna, circulator, low-noise amplifier, combiner, mixer, band-pass filter, gain controllable amplifier, limiter and An analog-to-digital converter forms the receive channel. The detection device of the present invention is small in size and light in weight, and can be mounted on an unmanned aerial vehicle to realize rapid detection of trapped persons in a large area, and has stronger environmental adaptability and applicability.

Description

technical field [0001] The invention relates to radar radio frequency and signal processing technology, and mainly relates to life detection radar signal processing and antenna radio frequency circuit design and use. Background technique [0002] Life detection radar is the product of the combination of modern radar technology and biomedical engineering technology. Through electromagnetic waves penetrating non-metallic shielding media, such as reinforced concrete and brick-concrete ruins and other obstacles, it detects the life information of human survival, such as breathing, heartbeat and other information caused by human life activities. The airborne life detection system adopts the flexible characteristics of UAVs to quickly search disaster areas, and uses non-contact life detectors to search for trapped people. Its application scenarios are very extensive. [0003] The life detection radar emits electromagnetic waves, adopts ultra-wideband radar non-contact life featur...

Problems solved by technology

[0005] Products at this stage cannot realize airborne detection. For example, the publication number is CN105496359A, and the publication date is 2016-04-20. Poor capability and strong environmental interference; the publication number is CN103027670A, and the publication date is 2013-04-10. The invention name is a micro-power impulse type biological radar front end. The detection distance of this MIR life detection radar is relatively short, and it generally penetrates walls. About 2m away from Wei

These current products cannot meet the requirements of airborne radar with strong anti-jamming ability, long detection distance and strong penetrating ability, so airborne life detection radar still has great research value
