Distributed passive detection system based on cellular mobile communication base station and network thereof

Abstract

The invention provides a distributed passive detection system based on a cellular mobile communication base station and a network thereof. The system comprises an intercept receiving unit, a communication link and a master control center, wherein the intercept receiving unit comprises an antenna unit, a radio frequency signal processing unit, a baseband signal processing unit, a synchronous time service unit and a communication service unit; and the master control unit comprises a communication service unit, a data fusion unit, a target positioning / tracking unit, a target identifying unit, an integrated display control unit, a binary search decision unit and an intercept receiving equipment managing unit. The distributed passive detection system based on the cellular mobile communication base station and the network thereof provided by the invention is easy for wide arrangement, and has wide coverage range and good destruction resistance and elusive.

Description

technical field [0001] The invention relates to the field of passive detection, in particular to a distributed passive detection system based on a cellular mobile communication base station and its network. Background technique [0002] In modern high-tech warfare where electronic interference is increasingly complex, how to further improve the radar's "four resistances" (anti-jamming, low-altitude penetration, anti-radiation missile and anti-stealth) capabilities is an important goal for the development of new system radars. [0003] The passive radar receives the direct wave from the target radiation source and the reflected wave or scattered wave carried by the external radiation source after the target is irradiated by the antenna through the antenna (including Doppler frequency shift, time difference and angle of arrival of multi-station receiving signals, etc.), Target positioning and tracking are completed after information processing. It does not emit any radiation i...

Problems solved by technology

[0004] like figure 1 As shown, a passive radar detection scheme provided by the current traditional detection method is composed of several reconnaissance stations temporarily arranged in the protection area, and each reconnaissance station is interconnected through temporary wired or wireless communication, so this method is not easy Large-scale deployment, limited protection area, limited ability to detect and track targets, and cannot be unattended
