Abstract

Diffused whistlers recorded at low latitude station Varanasi (geom. lat. = 14°55′N, L = 1.07) India on January 11, 1998 have been analyzed using digital matched filtering and parameter estimation technique to achieve high accuracy in the determination of whistler and medium parameters. This is the first example of the analysis of diffused whistlers using matched filtering technique from low latitudes. It is found that path of propagation of these whistlers are anomalously far from the receiving station. Further, there is no correspondence between their low dispersion value and derived high L-value.
