Stochastic Geometry-Based Performance Analysis of Cellular Systems in the Vicinity of Rotating Radars

This letter analyzes the performance of a cellular system that shares spectrum with a nearby rotating radar. The analysis is based on stochastic geometry and combines opportunistic with concurrent spectrum sharing. We derive expressions for the cellular probability of coverage taking into consideration the radar guard zone and the operating parameters of both the radar and the cellular system. Results show that allowing eNBs inside the radar guard zone to operate when not in the radar beam improves the coverage and service of the cellular system compared to the case of a strictly silent guard zone.
