Night vision system based on WCDMA signal as well as implementation method thereof

Abstract

The invention relates to a night vision system based on a WCDMA signal as well as 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 transmitted from a UMTS base station and a second radio frequency signal returned from an observation area and outputting a first signal and a second signal after amplification, filtering and analog-to-digital conversion are performed; the communication module is used for transmitting the first signal and the second signal, which are output by the signal receiving module, to the software module; the coordinate receiving module is used for acquiring real-time coordinates of the night vision system and transmitting to the software module; and the software module comprises first to seventh sub modules and is used for performing a series of processing on the first signal and the second signal and performing two-dimensional time domain filtering processing by combining the real-time coordinates, acquired by the coordinate receiving module, of the night vision system and coordinates of the UMTS base station, thus an image of the observation area is acquired. The night vision system provided by the invention can solve the problems that image resolution of an existing night vision system is low and price of the existing night vision system is high.

Description

technical field [0001] The invention relates to a night vision system based on WCDMA signals and a realization method thereof, in particular to a system and a realization method thereof for nighttime target imaging using WCDMA 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 c...
