Abstract

The application relates to an anti-interference navigation decoy system, which comprises a navigation decoy host, an anti-interference antenna array and an anti-interference module. The navigation decoy host has a receiver structure and a navigation decoy system structure, can emit preset signals to a UAV, and receives signals processed by the anti-interference antenna array and the anti-interference module. The anti-interference antenna array is located on the upper part of the navigation decoy host and can receive satellite navigation signals from different directions in all directions. The application ensures that the satellite navigation signals can be stably and reliably monitored and received under a complex interference environment, greatly expands the application range and reliability of the system. The application can accurately detect and suppress various interference signals, effectively prevents deception signals, ensures stable operation of the system in a complex electromagnetic environment, and continuously and effectively implements decoy operation on a target receiver.
