IMPROVED APPROACH FOR METEOR DETECTION & AUTOMATION: A CROSS CORRELATION METHOD

Abstract: A simple but effective technique has been proposed for Atmospheric Radar signals to extract the sporadic events such as the meteor occurrences is presented at higher altitudes. VHF radars are also being used to detect the ionized meteor trail over the altitude region of 70-120 km as a tracer of background wind using correlation technique. The proposed cross correlation-based technique not only detects the occurrence of the meteor phenomenon, but also senses precisely the height at which the phenomenon observed. Correlation between the data collected from the successive range Bins is the basis for the meteor detection. This helps to automate for detecting the sporadic phenomenon.
