EXTENSION OF NOSE WHISTLER ANALYSIS

Abstract

A method is outlined for obtaining F sub N and T sub N, t e nose frequency and the time delay to the nose, for whistlers that do not exhibit a nose on the spectrographic records. The method is based upon a universal whistler dispersion function which is a function of f/F sub N only. Two time-delay measurements, at widely separated frequencies, are made on a whistler trace, and from this information and the universal dispersion function, F sub N and T sub N are obtained. Results of applying the method to actual nose whistlers are tabulated and show good agreement between calculated and measured values of F sub N and T sub N. A method of whistlersource identification is outlined which utilizes approximate information on nose frequency and is particularly useful for middle-latitude whistlers. (Author)
