Abstract:

In 1958, a number of missile launches from Cape Canaveral were monitored with a horizontally polarized, 220-Mc air-search radar at Miami, Florida, in a search for signal properties that could be attributed to an ionized exhaust trail. Observations were limited by the antenna pattern and ground reflections to the first three interference lobes covering height intervals of approximately 5 to 10, 15 to 25, and 30 to 38 nautical miles. While no enhancement effects were seen, the character of the signal changed somewhat with height, suggesting the importance of extending the measurements to greater altitudes. The missile study will be continued with the aid of a sensitive 140-Mc radar to be installed at the Chesapeake Bay Annex during 1961. Author
