AbstractAs modern battlefield scenarios require increasingly greater radio frequency (RF) capabilities from US Army ground vehicles, there is a corresponding requirement to develop antenna systems that ensure the mutual interoperability of these functions. Currently, there is an urgent requirement to address this challenge for two essential RF capabilities: communications and electronic warfare (EW). Communications systems tend to operate at relatively low power levels, and with relatively high sensitivities for both transmit and receive functions. EW systems have comparable sensitivity requirements in their receive modes, but often require very high power levels in their transmit modes to perform their intended function. Because of the mutual sensitivities of the two systems, their simultaneous operation in the necessarily-close proximity afforded by typical US Army ground vehicles is a significant challenge that is not being adequately addressed in current systems. In the proposed Phase II effort, FIRST RF will continue investigation of the isolation techniques demonstrated during Phase I, including options exploiting interaction properties in the spatial, temporal, and spectral domains. To allow government evaluation, FIRST RF will provide prototype hardware and support technical demonstrations at three intervals in the Phase II program.
