The objective of this SBIR program is to provide improved reliability and predictability of HF communications using either Skywave or Near-Vertical Incidence Skywave (NVIS) propagation modes at bit rates exceeding 100 kbps to overcome the shortfall in long-range tactical communications in complex terrain environments. In this Phase II effort, GIRD Systems continues the development of its innovative and novel HF wideband waveform to achieve data rates well above the 100kbps requirement in NVIS channels. This effort will focus on implementation of a prototype software defined radio which will be demonstrated with over-the-air testing to confirm its performance.
