Committee on Radio Frequencies CORF represents the interests of U.S. scientists who use radio frequencies for research—for example, radio astronomers and remote sensing researchers. The committee deals with radio-frequency requirements and interference protection primarily through filing comments under the aegis of the National Academy of Sciences in public proceedings of the Federal Communications Commission. The committee acts as a channel for representing the interests of U.S. scientists in the work of the Scientific Committee on Frequency Allocations For Radio Astronomy and Space Science (IUCAF) of the International Council for Science and in working groups of the Radiocommunication Sector of the International Telecommunication Union (ITU).

Caryn J. Knutsen, Program Associate Current Report-writing Activities The committee, A Survey of the Scientific Uses of the Radio Spectrum, has been appointed. The current system of allocating bands in the radio spectrum was developed over fifty years ago, and a review of the needs of scientific users is in order. In recent years, the explosion of new wireless technologies has significantly increased the demand for access to the radio spectrum. The increased demand has led to discussions in both government and industry about new ways of thinking about spectrum allocation and use. Scientific users of the radio spectrum (such as radio astronomers and earth scientists using remotely sensed data) have an important stake in the policies which will result from this activity. This survey of the scientific uses of the spectrum will identify the needs of today’s scientific activities and assist spectrum managers in balancing the requirements of the scientific users of the spectrum with other interests. The survey will be carried out by an NRC committee over a period of 18 months. Past Report-writing Activities Related Non-NRC Publications Related Items of Interest Ocean Radar
The audio recordings listed below are demodulated sounds of ocean radars operating in the HF bands. These particular recordings were acquired at a frequency of 4540 kHz. One file was acquired with the receiver in upper sideband mode (filter bandwidth approximately 3 kHz), the other was acquired in AM mode (approximately 12 kHz bandwidth). The overall bandwidth of the transmitted signal was measured to be about 50 kHz. Further information on ocean radars can be obtained from the web site of one of the manufacturers (CODAR), at www.codar.com.
