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

The present application provides a method and system for controlling a millimeter-wave antenna array, wherein the system includes: a control device and an antenna array, and the antenna array includes: a CPLD, N switch circuits, and N antenna units; the control device is used to send the first signal; the CPLD is used to switch the first switch circuit in the N switch circuits to the on state according to the preset sequence according to the first signal, and switch the second switch circuit before the first switch circuit in the preset sequence to the off state . The method and system for controlling a millimeter-wave antenna array provided by the present application can reduce the working time of a single scan of the antenna array and improve the scanning efficiency of the millimeter-wave antenna array.
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...
