Abstract

This invention discloses a satellite signal interference monitoring method for low-altitude critical infrastructure, comprising: a satellite signal acquisition module, a satellite signal interference intensity assessment module, and a risk level assessment module. The satellite signal acquisition module acquires satellite signals through a fixed satellite signal receiving terminal and performs preprocessing. The satellite signal interference intensity assessment module extracts different features and establishes a satellite signal interference decision model. The risk level assessment module, based on the satellite signal interference intensity value and the urgency of the UAV flight mission, constructs a dynamically weighted risk level assessment model for UAV safe flight under satellite signal interference, dynamically assesses the satellite signal interference risk level in real time, and generates intelligent early warning signals. This invention, based on the satellite signal interference intensity value and the urgency of the UAV flight mission, designs a UAV flight safety risk level assessment model, solving the problem of difficulty in quickly quantifying the risk level of UAV flight under signal interference conditions.
