摘要：
Low Earth orbit (LEO) mega-constellations are promising enablers of 6 G networks, offering high throughput, low latency, and global coverage. However, their low orbital altitude, publicly accessible ephemerides, and open wireless channels render them particularly vulnerable to uplink jamming attacks. While the massive number of LEO satellites provides spatial diversity that can be exploited through flexible user association for jamming mitigation, the resilience of such large-scale constellations against organized, coordinated jamming remains unexplored. This paper investigates the uplink performance of LEO mega-constellations under large-scale jamming attacks and derives a tractable expression for outage probability and average throughput using stochastic geometry. Numerical results reveal that when user association is fixed and known to adversaries, increasing satellite density yields negligible anti-jamming gains. In contrast, under flexible association unknown to jammers, the jammer density must scale with the satellite density to maintain a given outage probability, highlighting the effectiveness of flexible user association in enhancing network resilience.
