EQUIPMENT TO CHARACTERIZE THE MARITIME RF ENVIRONMENT
Abstract
We propose to procure equipment to support the characterization of the maritime radiofrequency (RF) environment. Propagation perfo"rmance varies widely as a result ofspatiotemporal variation in the environment. The ocean surface wave field and theunderlying ocean surface currents Doppler shift Bragg waves and therefore create acomplex scattering environment at the air-sea interface. Profiles of refractivity of thepropagation medium vary, including variability in the ionosphere ~ the upper boundary ofRF propagation and phenomena responsible for creating ~sky wave~ propagation. Therelative influence of these variations depends on the radio frequencies of interest, but arebound by a common set of physical processes which depend on the environment. Theproposed suite of instrumentation will allow us to pursue Naval-relevant basic sciencestudies of the propagation environment and consists of the following: a) an array of GPSbaseddrifting wave buoys, b) High Frequency (HF) Radar equipment to map oceancurrents to understand Doppler shift of Bragg Waves c) an ionospheric sounder to exploretemporal variations in the ionosphere and the impacts to high frequency RF propagation,and d) computational infrastructure to fuse sensor data, perform numerical wave forecasts,and characterize links between" the surface wave field and RF propagation.
