Low, slow and small target navigation spoofing device and method

Abstract

The invention discloses a low, slow and small target navigation spoofing device and method. The low, slow and small target navigation spoofing device and method solve the problem of potential safety hazards of low, slow and small target interception of an existing device and method. The device comprises a detection module, a GPS receiver, a navigation signal simulator and a navigation signal transmitter. The detection module is used for receiving a target echo in real time and outputting target information; the GPS receiver is used for receiving GPS signals, solving the output GPS time, a realsignal navigation telegraph text, signal amplitude, and GPS receiver location; the navigation signal simulator is used for receiving the GPS time, the real signal navigation telegraph text, the signal amplitude, and outputting a GPS spoofing signal with combination of trajectory requirements of the spoofing process; and the navigation signal transmitter is used for adjusting the power of the GPSspoofing signal according to the position of the GPS receiver to radiate into space. The method is used for generating the GPS spoofing signal by the device. The device and method achieves spoofing signal generation of a low, slow and small target with anti-interference measures.

Description

technical field [0001] The invention relates to the field of interception and capture of unmanned aerial vehicles, in particular to a device and method for navigating and deceiving low-slow and small targets. Background technique [0002] With the growing market of UAVs, the threats to public safety from low-slow and small targets are also becoming more and more serious. The existing interception of low-slow and small targets is mainly divided into two categories: interference and destruction. The destruction mainly uses missiles and lasers. Weapons, microwave weapons, combat drones, and conventional firepower directly destroy slow and small targets, but the target may cause collateral damage when it falls. The interference category cuts off the communication between the UAV and the remote control platform by transmitting directional high-power interference radio frequency to the UAV, forcing the UAV to hover, land or return. This method is simple and effective, but the inte...
