Abstract : This report describes a computer model for predicting the performance of meteor burst communication links in terms of the usable meteor rate (MR) and the available channel duty cycle (DC). This model incorporates an empirical database of sporadic meteor flux, an empirical meteor velocity distribution, and detailed antenna pattern data usually provided by the National Electromagnetics Code (NEC). This program, PC METEORLINK, integrates MR and DC contributions throughout the sky region between 80 and 120 km above the earth's surface where most meteors are ionized. PC METEORLINK was derived from a VAX FORTRAN program called METEORLINK. This report describes the algorithms used in PC METEORLINK, the empirical data of meteor flux and velocity, the empirically-based formula for various meteoric physics and atmospheric parameters. It is divided into three sections. The first, R&D Equipment Information, is a User's Guide for the PC METEORLINK program. The second, Computer Software Product Item, is a Technical Manual for the program. The third, Scientific and Technical Report, presents validation results for PC METEOR- LINK prediction. This validation section compares PC METEORLINK predictions with data taken from the Greenland Meteor Burst Test Bed, the Jodrell Bannk Experimental Station, and meteor-burst measurements performed in Kazan, Russia.
