Digital video satellite signal based night vision system and implementation method thereof

Abstract

The invention relates to a digital video satellite signal based night vision system and implementation method thereof. The system includes a signal receiving module used for receiving first radio frequency signals sent from a ground digital television base station and second radio frequency signals returned from an observation area, and outputting first signals and second signals through amplification, filtering, and analog-digital conversion; a communication module used for transmitting the first signals and the second signals output by the signal receiving module to a software module; a coordinate receiving module used for acquiring real time coordinates of the night vision system and transmitting the real time coordinates to the software module; the software module including a first submodule, a second sub module, a third sub module, a fourth sub module, a fifth sub module, a sixth sub module, a seventh sub module, an eighth sub module and a ninth module used for a series of treatment on the first signals and the second signals and performing two-dimensional time domain filtering treatment on the system real time coordinates acquired by the coordinate receiving module and digital video satellite coordinates, and observing images in the observation area. The system and method provided by the invention can solve problems of low image resolution and high system price of a prior night vision system.

Description

technical field [0001] The invention relates to a night vision system based on digital video satellite signals and its realization method, in particular to a system and its realization method for nighttime target imaging using digital video satellite signals, and belongs 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 ...
