Ambient light scattered from metal oxide particles in composite-propellant rocket exhausts makes the missile trail visible at long ranges. In the selection of propellant aluminum concentration, it is important to be able to predict the distance from which the exhaust no longer is visible. In this paper, a simple methodology, amenable to hand calculation, is presented for this purpose. The user need supply only the propellant aluminum concentration, missile velocity and altitude, and the rocket motor thrust level. The methodology predicts smoke trail dimensions, particle concentration as a function of location in the trail, sunlight and skylight scattering, background obscuration, and the range at which the trail may be detected visually for any atmospheric attenuation level. The entire calculation can be carried out with a scientific pocket calculator.read more

Effects of Multiple Scattering on Rocket Exhaust Plume Smoke Visibility
TL;DR: In this article, an approximate method of solution for the scattering of radiation by optically thick media is described, where multiple scattering functions analogous to single scattering functions are derived by a Monte Carlo technique.

Plume, Signal Interference and Plume Signature
TL;DR: In this paper, the authors present plume signature and signal interference in the case of a solid-propellant rocket motor and demonstrate that the plume or smoke reveals the launch location of a missile and allow the missile to be located in flight.

Prediction of the visible signature of solid rocket plumes
TL;DR: In this article, the visible contrast of a rocket plume against the sky produced by scattering of sunlight and sky light by primary and secondary smoke in the plume is defined. And the analytical procedure is encoded in a computer program, VISIG, suitable for use on a microcomputer.
