Automated Spectrogram Analysis for Meteor Head Echoes
Abstract
The Meteor Echo Spectrogram Analysis (MESA) program is developed to automatically identify meteor head echoes in spectrograms generated by forward-scatter radio meteor detection. The program is both extensible and flexible, allowing calculations such as line-of-sight approach and recede velocities, duration, and maximum intensity. A detection sensitivity of 0.790 is achieved, with an improved sensitivity of 0.875 when only low-noise spectrograms (about 2/3 of the data) are analysed. The MESA program cannot fully replace manual analysis of spectrograms, but greatly reduces the volume of data that needs processing.
