The temporal variations of interference power due to periodic rotations of radar antenna and the interference attenuation resulting from frequency separation can substantially contribute to the link loss. Consequently, even in the scenario where cellular devices are fairly close to radar, there still will be periods of time when the link loss is high enough such that cellular systems can take opportunity to transmit while without interfering with radar. Numerical results show that in the scenario where spectrum sharing between a single cell and single rotating radar is considered, although with some interruptions, the communications system can achieve its data rate limit within a range that is a few kilometers away from the radar.Read More
