Abstract

Abstract:

Aiming at the problem that conventional single-node jamming methods struggle to counter the spatiotemporal complexity of mega-constellations, a distributed jamming strategy for mega-constellations is proposed, and a mathematical model for jamming analysis targeting the downlink of mega-constellations is established. A grid-based deployment approach for jammers is adopted to enhance the spatial distribution flexibility of the adversarial side, along with a jamming probability calculation method and a jamming effectiveness evaluation metric. Based on actual satellite operation data, taking the Starlink system as an example, the jamming coverage range is calculated under different conditions of radio frequency power, grid spacing, and antenna radiation patterns. Simulation results show that when the node transmission power is 26 dBW, the average jamming coverage per node can reach 38.5 km2, providing support for the regulation and management of mega-constellations.

Key words: distributed jamming, mega-constellation, downlink transmissions, modeling and simulation, jamming evaluation method
