Abstract
The invention relates to a radar test system, and in particular to a millimeter-wave radar sensor, applied to medical monitoring equipment. The millimeter-wave radar sensor comprises a dot-frequency millimeter-wave phase controlled oscillator, a directional coupler, a circulator, a frequency mixer, a power amplifier, a radar transmitting and receiving antenna, a signal processor and a monitoring terminal; through the coupler and the circulator, the signal processor is in charge of transmitting a millimeter-wave signal, which is generated from the dot-frequency millimeter-wave phase controlled oscillator, by virtue of the radar transmitting and receiving antenna; the millimeter-wave signal reaches the body surface of a monitored patient and enters into the body of the monitored patient; the millimeter-wave signal, which is returned, is received by virtue of the radar transmitting and receiving antenna; the millimeter-wave signal, which is processed by virtue of the frequency mixer and the power amplifier, reaches the signal processor which is in charge of processing the feedback signal (the millimeter-wave signal); and a processing result is displayed by virtue of the monitoring terminal, so that disease detection is identified by virtue of millimeter wave.
Description
Technical field
The present invention relates to Radar Measurement System, more particularly, to a kind of millimetre-wave radar sensor.
Background technology
Millimeter wave refers to electromagnetic wave between 1 ~ 10mm for the wavelength, and its radio frequency band is roomy, high resolution, in recent years, in the least

Ring, and, it is also applied to unmanned plane radar, medical treatment, intelligent lighting etc..
But, medically utilize this millimeter wave identification state of an illness very difficult in prior art, usually report by mistake.
Content of the invention
Embodiments provide a kind of millimetre-wave radar sensor, solve and in prior art, medically utilize this milli
The metric wave identification state of an illness is very difficult, the technical problem usually reported by mistake.
In order to solve above-mentioned technical problem, embodiments provide a kind of millimetre-wave radar sensor, be applied to cure
Treat in monitoring device, including point frequency millimeter wave phase controlled oscillator, directional coupler, circulator, frequency mixer, power amplifier, thunder
Reach dual-mode antenna, signal processor, monitor terminal, described signal processor is to the milli being produced by a frequency millimeter wave phase controlled oscillator
Metric wave signal is launched by radar transmit-receive antenna by coupler, circulator, reaches the body surface of monitored patient, goes forward side by side
Enter the body interior of monitored patient, received by radar transmit-receive antenna through feedback, and through frequency mixer, power amplifier reaches letter
Number processor, signal processor is processed to this feedback signal, and result is shown by monitor terminal.
Further, described processor is used for the signal of monitored personnel's body interior feedback being carried out separate, and extracts, and
Shown by monitor terminal.
Further, described monitor terminal also includes memory, for storing the testing result of different monitored patients.
The embodiment of the present invention at least has the following technical effect that or advantage：
Due to adopting a point frequency millimeter wave phase controlled oscillator, directional coupler, circulator, mixing in this millimetre-wave radar sensor
Device, power method seven, radar transmit-receive antenna, signal processor and monitor terminal, can be effective to the state of an illness of monitored patient
Analysis and monitoring, and then can be detected using this millimeter wave identification state of an illness.
Brief description
Fig. 1 is the module diagram of millimetre-wave radar sensor in the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention is passed through to provide a kind of millimetre-wave radar sensor, solves medically to utilize in prior art and is somebody's turn to do
The millimeter wave identification state of an illness is very difficult, usually reports by mistake.
In order to solve above-mentioned technical problem, below in conjunction with Figure of description and specific embodiment to above-mentioned technology
Scheme is described in detail.
Embodiments provide a kind of millimetre-wave radar sensor, frequency millimeter wave is phased to shake as shown in figure 1, inclusion is put
Swing device 10, directional coupler 20, circulator 30, frequency mixer 40, power amplifier 50, radar transmit-receive antenna 60, signal processor
70th, monitor terminal 80, this signal processor 70 is fixed to being passed through by a millimeter-wave signal that frequency millimeter wave phase controlled oscillator 10 produces
Launched by radar transmit-receive antenna 60 to coupler 20, circulator 30, reach the body surface of monitored patient, and enter quilt
The body interior of monitoring patient, is received by radar transmit-receive antenna 60 through feedback, and through frequency mixer 40, power amplifier 50 reaches
Signal processor 70, signal processor 70 is analyzed to this feedback signal processing, and result is passed through monitor terminal 80
Shown.Enable the surgeon to see the condition of detection.
Specifically, this signal processor 70 is used for the signal of monitored personnel's body interior feedback being carried out separate, extracts,
And shown by monitor terminal 80.
This monitor terminal 80 also includes memory, for storing the testing result of different monitored patients.So, it is easy to cure
Life effectively can be grasped to the state of an illness of patient.
Although preferred embodiments of the present invention have been described, but those skilled in the art once know basic creation
Property concept, then can make other change and modification to these embodiments.So, claims are intended to be construed to including excellent
Select embodiment and fall into being had altered and changing of the scope of the invention.
Obviously, those skilled in the art can carry out the various changes and modification essence without deviating from the present invention to the present invention
God and scope.So, if these modifications of the present invention and modification belong to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprise these changes and modification.
