A description of the University of Illinois meteor radar system and some first results

A recently established meteor radar system for observing motions in the upper atmosphere is described, which features a peak transmitter power of 5 megawatts. This large peak power should allow a much greater number of wind determination during a fixed period of time than other meteor radar stations. The essential features of the range algorithm, two velocity algorithms, and the interferometer phase difference algorithm in use are described. A typical measured variation in the radial southward wind as a function of time of day based on data from all altitudes is shown as an example, and some results of spectral analysis of the data, yielding amplitude and phase variation with altitude for significant waves, is discussed.
