摘要：
An ionospheric condition monitoring system (ICMS) is a critical component of over-the-horizon radar (OTHR), providing advice on frequency channel selection and availability for operation. Because of dynamically changing atmospheric, ionospheric and magnetic conditions, the over-the-horizon radar (OTHR) transmit carrier frequency needs to be adjusted regularly to maintain constant illumination of targets downrange. The OTHR must also operate in frequency channels that are not currently occupied by other users. In this study, methodologies are developed to determine feasible radar parameters such as operating frequencies and elevation angles for OTHR operation using a 3-dimensional ray-tracing technique. Preliminary results suggest that a 3-dimensional ray-tracing technique can be used to provide the basis for the way ahead in exploring OTHR applications in Canada.
