Spectrum sharing is an elegant solution to the problem of spectrum scarcity. A novel advanced approach is developed in this study to enable power-controlled cellular networks coexist with primary rotating radars. A canonical scenario is considered where a single cellular BS interferes with single rotating radar. A new mathematical model is also developed using log-normal approximations to capture the aggregate interference from multiple power-controlled cellular systems. The cellular system transmits at high power for over 83.3% of time due to the slow radar antenna rotation and narrow main beam width. Our numerical results show that the power control drastically reduces the required separation distances between the two systems. The log-normal approximation gives results which virtually match the results of our simulation.
