Short-term characterisation of hydrometeor scattering channel

The problem of hydrometeor scatter at oblique angles is central in assessing the magnitude of interference between two independent radio communication systems operating in the same frequency band. A large portion of the frequency spectrum is re-used by various services and in these bands hydrometeor scatter constitutes one of a number of interference mechanisms which could result in a degradation of the quality of service. Scatter of this type causing co-channel interference can be classified as bistatic inter-system co-channel interference. To assess the systems importance of hydrometeor scatter (especially with respect to BER in digital communications systems) a simulator which generates signals with the correct temporal and spectral characteristics has been developed. The first-order statistical characteristics in time and frequency domains for CW transmissions have been found using the simulator and tested against known results as a method of simulation validation.<
