Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] The millimeter-wave imaging system is mainly divided into millimeter-wave active imaging and millimeter-wave passive imaging. The advantage of this passive millimeter-wave imaging system is that the structure is relatively simple, and the implementation cost is also low. The disadvantage is that the imaging time is too long and the imaging resolution is poor. With the improvement of the level of millimeter-wave devices and the development of millimeter-wave device technology, millimeter-wave active imaging has begun to receive more and more attention. In millimeter-wave active imaging, acti...

Abstract

The invention provides a millimeter wave holographic three-dimensional imaging detection system. The millimeter wave holographic three-dimensional imaging detection system comprises a transmitting antenna, a receiving antenna, a millimeter wave receiving / transmitting module, a scanning device, a data acquisition and processing module and an image display unit, wherein the transmitting antenna is used for transmitting a millimeter wave transmitting signal to an object to be detected; the receiving antenna is used for receiving an echo signal returned by the object to be detected; the millimeter wave receiving-transmitting module is used for generating the millimeter wave transmitting signal transmitted to the object to be detected, and receiving and processing the echo signal from the receiving antenna; the scanning device is used for fixing and moving the millimeter wave receiving-transmitting module, the transmitting antenna and the receiving antenna; the data acquisition and processing module is used for acquiring and processing the echo signal output by the millimeter wave receiving-transmitting module to generate a three-dimensional image of the object to be detected; the image display unit is used for displaying the three-dimensional image generated by the data acquisition and processing module. Furthermore, the invention further provides a millimeter wave holographic three-dimensional imaging detection method of the object to be detected by utilizing the millimeter wave holographic three-dimensional imaging detection system. The millimeter wave holographic three-dimensional imaging detection system provided by the technical scheme has the advantages of simple structure, high resolution ratio, short imaging time, relatively large view field and the like.

Description

technical field [0001] The invention relates to a millimeter-wave holographic three-dimensional imaging detection system and method, in particular to a millimeter-wave three-dimensional imaging system and method based on linear frequency modulation technology, superheterodyne detection principle and holographic imaging principle. Background technique [0002] The frequency of millimeter wave is 30GHz to 300GHz (wavelength from 1mm to 10mm). In practical engineering applications, the low-end frequency of millimeter wave is often reduced to 26GHz. In the electromagnetic spectrum, millimeter wave frequencies lie between microwaves and infrared. Compared with microwaves, the typical characteristics of millimeter waves are short wavelength, wide frequency band (with a very wide utilization space) and propagation characteristics in the atmosphere. Compared with infrared, millimeter wave has the ability to work around the clock and can be used in harsh environments such as smoke, ...
