Abstract

The present invention is applicable to the technical field of radar imaging, and provides a millimeter-wave-based imaging method, device, device, and storage medium, wherein the millimeter-wave-based imaging method includes: receiving an echo signal of a target to be imaged; traversing and calculating the echo signal The contrast function of all preset three-dimensional coordinate points of the signal in the preset three-dimensional space area; wherein, the preset three-dimensional space area is constructed based on the preset frequency interval, the preset transmitting position interval and the preset receiving position interval, and the preset frequency interval is The frequency range of the transmitting signal of the imaging device, the preset transmitting position interval is the position interval of the transmitting antenna of the imaging device, and the preset receiving position interval is the position interval of the receiving antenna of the imaging device; the contrast function of all preset three-dimensional coordinate points is performed The sum is obtained to obtain the target contrast function of the target to be imaged; according to the target contrast function, an image of the target to be imaged is generated. The imaging precision can be improved by adopting the invention.

Description

Millimeter-wave-based imaging method, apparatus, device, and storage medium technical field The invention belongs to the technical field of radar imaging, in particular to a kind of imaging method, device and equipment based on millimeter waves and storage media. Background technique [0002] With the rapid development of millimeter wave technology, the application fields of millimeter wave technology are also becoming wider and wider, such as the field of security inspection. Millimeter wave human body security inspection device is a kind of human body security inspection equipment, which can use the penetrating ability of millimeter wave to ordinary clothes to detect. image to determine whether the body surface of the inspected body is hiding suspected objects. In terms of antenna distribution, the millimeter-wave human body security detector can It is divided into line scan structure and area scan structure. At present, the line scan structure is more developed at ...
