Multistatic Coordinated Multipoint ISAC for Automotive Scenarios with Binary Integration

International Radar Symposium, pp. 1–6

Abstract

This paper presents a comprehensive comparison of all multistatic sensing configurations within Coordinated Multipoint (CoMP) Integrated Sensing and Communication (ISAC) systems for an automotive intersection scenario. An OFDM-based simulation framework is developed to evaluate monostatic, bistatic, and multistatic sensing schemes under binary integration using various$m$-of-$n$fusion rules. Simulation results demonstrate that full multistatic sensing significantly enhances sensing performance, improving coverage from 20% in the standalone monostatic configuration to 80%, corresponding to a fourfold increase, while the average probability of detection increases from 0.25 to 0.83 over the entire sensing area. These results confirm that cooperative sensing substantially improves detection reliability and coverage without incurring high communication overhead. Furthermore, the results highlight the trade-off inherent in the fusion logic, where smaller values of$m$favor coverage extension, while larger values of$m$improve detection robustness.
