Armoured Fighting Vehicle Team Performance Prediction against Missile Attacks with Directed Energy Weapons
share
A recent study has introduced a procedure to quantify the survivability of a team of armoured fighting vehicles when it is subjected to a single missile attack. In particular this study investigated the concept of collaborative active protection systems, focusing on the case where vehicle defence is provided by high power radio frequency directed energy weapons. The purpose of the current paper is to demonstrate how this analysis can be extended to account for more than one missile threat. This is achieved by introducing a jump stochastic process whose states represent the number of missiles defeated at a given time instant. Analysis proceeds through consideration of the sojourn times of this stochastic process, and it is shown how consideration of these jump times can be related to transition probabilities of the auxiliary stochastic process. The latter probabilities are then related to the probabilities of detection and disruption of missile threats. The sum of these sojourn times can then be used to quantify the survivability of the team at any given time instant. Due to the fact that there is much interest in the application of high energy lasers in the context of this paper, the numerical examples will thus focus on such directed energy weapons for armoured fighting vehicle team defence.
