Analysis of frequency sharing between mobile systems and radiolocation radars in VHF band

This paper provides the study results of separation distance for land mobile station from the space surveillance radar operating in VHF band using methodology given in Recommendation ITU-R M.1461. Recommendation ITU-R P.1546 model is used for calculation of propagation losses and time rate of 1% is applied. In this sharing study, protection criteria based on the interference-to-noise ratio are applied, I/N = -6 dB for general land mobile stations, and I/N = -10 dB for applications with greater protection requirements, such as public protection and disaster relief (PPDR).
