Abstract:

This report presents calculations by the Air Forces Geophysics Laboratory GL of waiting times for signals scattered from ionized meteor trails having durations between 50 and 400 msec. The calculations are based on a Signal-to-Noise Ratio SNR and bandwidth representative of a communication system using Binary Phase Shift Keying BPSK modulation with a Bit Error Rate BER of 10-3 and a signaling rate of 8000 bitssec. The computations are based on data obtained on the Geophysics Laboratorys High Latitude Meteor Scatter Test Bed in Greenland. Statistics of arrival rates, duty cycles, and durations for meteor scatter returns exceeding selected SNRs have been included for interpretation of the waiting time statistics. Statistics for the months of February, March, June, September, and December 1989 are included to evaluate the influence of seasonal variations on the waiting times.
