A Suggested Improvement to the C.W. Technique for Measurement of Meteor Velocities

Abstract

Radio methods of measuring meteor velocities, whether by pulse (Davies and Ellyett 1949) or C.W. techniques (Mckinley 1951), ultimately depend on a knowledge of the separation, along Cornu's spiral, between points representing any two maxima or any two minima of the echo waveform. The relation $$, where R0 is the minimum range of the echo and ? is the wavelength, enables these" zone values "$$ to be correlated with line segments s of the meteor trail.
