Optimum Pulse Duration for Electromagnetic Transmission During Atmospheric Reentry.
Abstract
The feasibility of increasing the maximum average electromagnetic power transmitted from a reentry vehicle by selecting an optimal rf pulse duration is examined. The pulse duration and the rf power level are chosen such as to avoid rf breakdown in the reentry plasma sheath. The analysis is kept general, but quantitative results for a realistic reentry antenna system are also presented. It is found that the choice of an optimum pulse duration allows only a small increase in average power. Advances in plasma alleviation techniques that would be needed to make the proposed system more than just marginally feasible are discussed. (Author)
