Direction finding technique for elliptically polarized VLF electro-magnetic waves and its application to the low-latitude whistlers

摘要: Abstract A new method for direction finding of elliptically polarized VLF electromagnetic waves has been developed. The uses simple algebraic relations between the vertical electric field and horizontal magnetic fields received to eliminate TE components field. present can give a reasonably accurate estimate angle incidence as well azimuth when incident wave is polarized, complementary classical goniometer which suited determination linearly waves. technique applied whistlers observed at Kakioka (26°N in geomagnetic latitude). results are: 1. (1) Most analyzed come from nearly directly overhead show small L R ratio. 2. (2) measured shows little frequency dependence especially range where sonagram trace continuous.
