Description
Summary:A high‐fidelity HF channel simulation has been developed that is suitable for Over‐the‐Horizon Radar (OTHR) and HF communication system design studies and test planning. The simulation capability is called HiCIRF, for High‐frequency Channel Impulse Response Function. HiCIRF provides simulated HF signals corresponding to transmissions from individual transmitter array elements to individual receiver array elements for propagation through the naturally disturbed or undisturbed ionospheric channel. Both one‐way link geometries and two‐way radar geometries can be simulated. HiCIRF incorporates numerical ray tracing and stochastic signal structure computations to realistically simulate signal scatter by small‐scale ionization structure. Stochastic signal generation is employed to generate signal realizations that can be used for OTHR array design and advanced signal processing studies. Key Points A high‐fidelity HF ionospheric channel simulation has been developed The simulation includes HF multimode and small‐scale scatter The simulation generates pulse‐by‐pulse channel impulse response realizations
