(25) a Matrix Approach to a Propagation Code - SlideRule - 01-27-2019 10:05 PM An extract from a Matrix Approach to a Propagation Code, AFIT (School of Engineering), Air University, DEC 1977 Appendix C Sample Calculator Programs The following pages contain two sample calculator programs for a single propagation scenario as an example of how the matrix formulation may be used on a hand calculator. The first program … The second program is designed for a Hewlett Packard HP 25. The propagation scenario that the programs solve is the co-altitude transmission of a laser beam from a transmitter to a receiver over a distance L in propagation steps of distance z. The beam has some initial power P and radius x and is assumed to be focused at a point distance L away. Because the effect of turbulence is small compared to thermal blooming, it is not included in these programs. If desired, however, it may be added. the HP-25 program starts on page 30. BEST!
