UWB (Ultra-Wide Band) based multi-information perception bioradar system and method thereof for obtaining target information

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...
