Abstract:

This document reports the results of Phase 2 of a two phase study program of HF Optimum Frequency Detection OFD Techniques. In the Phase 1 report, the preliminary study findings were discussed and a recommended OFD System described. This report on Phase 2, describes the results of a test program designed to determine the validity of the recommentations of Phase 1. In Phase 2, an OFD System and a communications system were operated over a point-to-pint and ground-to-air HF circuit and a performance evaluation of the OFD System made.
