Design and Analysis of Embedded Antennas for 60-mm Mortars; Final rept. Mar-Jun 2006

摘要

The Defense Advanced Research Projects Agency and the U.S. Army are engaged in a high-risk/high-payoff project for the development of precision- guided 60-mm mortars in support of the Optically Designated Attack Munition program. This report describes the antenna design and performance characteristics required for an embedded telemetry-based onboard diagnostic system, which was conceived and developed at the U.S. Army Research Laboratory in support of experimental testing phases of the program. Our primary objective to demonstrate rapid response and low-cost, reliable capability for projectile- mounted antennas compatible with commercially available telemetry products was successfully achieved. Aspects of the specific design such as the antenna radiation pattern characteristics at the operating frequency of interest, the radio frequency tuning process of the antenna array, and the returned in-flight signal strength along the trajectory from the resultant diagnostic system are included and summarized in this report.
