Abstract : The objective of this program, as given in the original JAYCOR proposal, has been to design experiments leading to the verification of diversity reception techniques for tactical C2 signal collection. The results of this design effort are summarized in this final report. The experimental program that has been designed is referred to in this report as the VHF Reception Program -- Phase II. Similarly, the program that has just been completed is referred to as the Phase I program. In the Phase I program, we have identified three key physics issues concerning diversity reception of meteor path propagation. These issues are: What is the gain vs. beamwidth tradeoff on a single receiver antenna? Can independent meteor propagation paths be obtained at a single location using multiple receiver antennas? and What spatial separation is needed to obtain independent paths from a common volume?
