Title:
FORWARDING TYPE SATELLITE NAVIGATION DECEPTION JAMMING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/016483
Kind Code:
A1
Abstract:
A forwarding type satellite navigation deception jamming system and method. The system comprises an antenna array device, a plurality of LNA modules, a plurality of forwarding processing modules, a civilian code capture tracking module, a civilian code guidance military code purification module, and a system general control and jamming generation module. According to the system, a plurality of high-gain antennas are arranged on a spherical surface to be responsible for receiving satellite signals in corresponding sub-regions, thereby solving the problems of high cost and high power consumption caused by the fact that a parabolic antenna and a phased-array antenna are used for the existing forwarding type satellite navigation deception jamming system for military navigation signal deception. Moreover, before military code data is extracted, part of the satellite signals which are actually deception jamming signals are eliminated according to the mapping relationship between the satellite numbers in observed quantity data and the corresponding sub-airspace, thereby ensuring the quality of forwarded signals, and ensuring the test jamming effect.
