Problems solved by technology

[0004] However, using the existing technology, in order to realize that the control device can send work instructions to different antenna units, it is necessary to determine the control value of each antenna unit in the antenna array and complete the control of each antenna unit before the control device controls the millimeter-wave antenna array to scan. The configuration of the antenna unit makes the configuration process of the control device more complicated when controlling the millimeter-wave antenna array, and the working time of the antenna array for a single scan is longer, which reduces the scanning efficiency of the millimeter-wave antenna array

Abstract

The invention provides a millimeter wave antenna array control method and system, the system comprises control equipment and an antenna array, and the antenna array comprises a CPLD, N switching circuits and N antenna units; the control equipment is used for sending a first signal to the CPLD; and the CPLD is used for switching a first switching circuit in the N switching circuits into an on stateaccording to the first signal and a preset sequence, and switching a second switching circuit in front of the first switching circuit in the preset sequence into an off state. According to the millimeter wave antenna array control method and system provided by the invention, the working time of single scanning of the antenna array can be reduced, and the scanning efficiency of the millimeter waveantenna array is improved.

Description

technical field [0001] The present application relates to electronic technology, and in particular, the present application relates to a method and system for controlling a millimeter-wave antenna array. Background technique [0002] Security inspection is one of the contents of port inspection and public safety inspection. Its main content is to check whether passengers and their luggage carry guns, ammunition, explosives, corrosion, poisonous reflective and other dangerous items, so as to ensure that aircraft, buses, passengers and public safety. [0003] Due to the good penetrability of millimeter waves to textiles, leather and other materials, the resulting images have higher spatial resolution, and the energy of millimeter waves is several orders of magnitude lower than that of X-rays, and will not cause ionization to biological tissues Injuries, the use of millimeter-wave security inspection systems for human body security inspections is widely used and has very stron...
