Embodiment Construction

[0071] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0072] Such as figure 1 As shown, the UWB-based multi-information sensing biological radar system of the present invention is composed of four systems, namely a transmitter system, a receiver system, an antenna system, and a control and processing system. After the transmitter system receives the work order from the control and processing system, it generates equal interval step frequency continuous wave UWB signals based on the constant temperature crystal oscillator, and sends them to the transmitting antenna after power division and frequency conversion amplification; the receiver system adopts superheterodyne structure, the bio-radar echo signal is mixed with the local oscillator to become an intermediate frequency signal, and the amplitude and phase information of the echo is obtained th...

Abstract

The invention particularly discloses a UWB (Ultra-Wide Band) based multi-information perception bioradar system and a method thereof for obtaining target information. The multi-information perceptionbioradar system comprises a transmitter system, a receiver system, an antenna system and a control and processing system, wherein the antenna system adopts the configuration of an array antenna with two transmitting antennas and four receiving antennas; the transmitter system is used for receiving a working instruction of the control and processing system, generating equally spaced step frequencycontinuous wave UWB signals on the basis of a constant-temperature crystal oscillator and sending the signals to the transmitting antennas; the receiver system is of a superheterodyne structure; a receiver sends a bioradar echo signal into the control and processing system; and the control and processing system comprises a spatio-temporal information processing module, a behavior information processing module and a physiological information processing module. Through adopting a step frequency continuous wave signal system, a multi-channel antenna array and a module information processing technique, the comprehensive perception, about the spatio-temporal, behavior and physiological information of a human body, of a bioradar is realized; and the information perception ability and the utilityvalue of the bioradar are improved.

Description

technical field [0001] The invention relates to the technical field of biological radar or radar life detection, in particular to a UWB-based multi-information sensing biological radar system and a method for acquiring target information. Background technique [0002] Bio-radar is a new-concept radar that takes life as the object of detection and perception. It is an emerging cutting-edge technology recognized by the international scientific and technological community. This technology uses electromagnetic waves emitted by special radar as a carrier, which can penetrate clothing, ruins, walls and other obstacles to detect the movement of human targets, or the micro-movement of the body surface caused by vital signs such as breathing and heartbeat, so as to realize target recognition and positioning. and information perception. Bio-radar has the characteristics of non-contact, strong penetrating power, and accurate positioning, and has broad application prospects in the fiel...
