Embodiment Construction

[0044] 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.

[0045] Embodiments of the present invention firstly disclose a method for wide-area long-distance target detection by millimeter-wave radar, such as figure 1 shown, including;

[0046] S101. Generate a millimeter wave beam for detection.

[0047] S102. Under preset timing control, the millimeter-wave beam is transmitted at a constant frequency by the target element in the antenna array corresponding to the current timing, and the radiation direction angles of different elements of the antenna array are different.

[0048] In the embodiment of the present invention, the antenna array is used to achieve full coverage of the target range at a fixed frequency point, so as to achieve large-angle target detection without additional mechanical structures and without cha...

Abstract

The invention provides a device for realizing millimeter-wave-radar wide-area long-distance target detection and a detection method. The device comprises an antenna array, an antenna array controller,a millimeter wave processing component and a signal control component. The antenna array is controlled by the antenna array controller. The millimeter wave processing component is connected to the antenna array through the antenna array controller. The signal control component is connected to the millimeter wave processing component. The radiation direction angles of the different array elementsof the antenna array are different. The antenna array controller is used to start a target array element corresponding to a current time sequence in the antenna array according to a preset time sequence. In the invention, through controlling the distance between adjacent radiation units, the antenna array capable of emitting wave beams with different directions is realized, and the structure of the acquired antenna array is light and compact; and simultaneously, a complex Butler matrix network, a radio frequency phase shifter and an amplifier can be prevented from using, which is good for designing and realizing.

Description

technical field [0001] The invention belongs to the technical field of radar communication and array signal processing, and is especially suitable for the application of long-distance and wide-area detection of multiple targets in a static or moving state; the invention specifically relates to the realization of millimeter-wave radar wide-area long-distance targets Detection device and detection method. Background technique [0002] The pros and cons of target detection technology directly affect the effect and accuracy of detection. In summary, the techniques for detecting targets can be divided into the following categories: [0003] First, ultrasonic, infrared, camera or microwave detection. The ultrasonic detection distance is too small and is easily affected by the environment and wind, so the application occasions are limited. Infrared technology has been widely used in automatic door opening and closing devices, but it is mainly used in indoor applications due to i...
