Embodiment Construction
[0092] In order to better understand the present invention, the content of the present invention is further illustrated below in conjunction with the examples, but the content of the present invention is not limited to the following examples. Those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms are also within the scope of the claims listed in this application.
[0093] figure 1 It is a schematic diagram of the imaging scene of the night vision system based on 4GLTE signals provided by the embodiment of the present invention. The system is deployed on the car 2, the car is driving forward, and the night vision area 3 is directly in front of the car. The 4GLTE base station 1 emits electromagnetic waves 360 degrees to the ground. The system obtains night vision images by signal processing the electromagnetic waves reflected from the night vision area 3 . This system can also be applied to various other vehicles...

The invention relates to a night vision system based on a 4GLTE signal and an implementation method thereof. The night vision system comprises a signal receiving module, a communication module, a coordinate receiving module, and a software module, wherein the signal receiving module is used for receiving a first radio-frequency signal emitted from a 4GLTE base station and a second radio-frequencysignal returned from an observation area, and outputting a first signal and a second signal after amplification, filtration and analog-digital conversion; the communication module is used for transmitting the first signal and the second signal output by the signal receiving module to the software module; the coordinate receiving module is used for obtaining a real-time coordinate of the night vision system, and transmitting the real-time coordinate to the software module; and the software module includes first to sixth sub-modules, and is used for performing a series of processing on the firstsignal and the second signal, and performing two-dimensional time domain filtration processing in combination with the system real-time coordinate obtained by the coordinate receiving module and a coordinate of the 4GLTE base station to obtain an image of the observation area. According to the night vision system based on the 4GLTE signal and the implementation method thereof provided by the invention, the problems of low image resolution and high system price of the existing night vision system can be solved.
Description
technical field [0001] The invention relates to a night vision system based on 4GLTE signals and its implementation method, in particular to a system and its implementation method for night target imaging using 4GLTE signals, which belong to the field of security technology. Background technique [0002] Night vision system is a kind of auxiliary system that helps users obtain sight at night. It is often used in cars, enabling drivers to obtain information about road conditions ahead at night or in low light conditions, and can provide drivers with early warning of potential threats ahead. [0003] Existing technical solutions related to night vision such as "CN-201520869666-Vehicle Night Vision System" and "CN201720709058 A Vehicle Night Vision System" all use infrared imaging technology, and their shortcomings mainly include: [0004] (1) The infrared night vision imaging system is an active system, including an infrared signal transmitter and receiver, and the cost is rel...
