“…The following will focus on that for HEL DEWs but it is worth observing that the discussion can be adapted quite easily to include HPRF DEWs. However, it is important to note that the propagation of a laser beam is subjected to a number of distortion and environmental attenuating factors, such as diffraction, jitter, atmospheric turbulence, scattering, scintillation and thermal blooming [20], [21].…”

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.

“…44 The given characteristics of the COIL make this laser ideal for special industrial and military applications. [45][46][47][48] The third decade of COIL investigations and development provides a good base for these applications, and well-developed projects already exist. The COIL has a potential for applications such as decommissioning and dismantling of nuclear reactors.…”

Advantageous features of Chemical Oxygen-Iodine Laser (COIL) for laser technologies have increased considerably activities of international COIL communities during past ten years. They have been focused on the advanced concepts of hardware designs of the COIL subsystems, and testing and scaling-up of existing laser facilities. Prospective special applications of COIL technology, both civil and military, have received a significant attention and gained concrete aims. The paper is introduced by a brief description of the COIL operation mechanism and key device subsystems. It deals then with presentation of some investigated advanced concepts of singlet oxygen generators, alternative methods for atomic iodine generation, a mixing and ejector nozzle design to downsize a pressure recovery system, and optical resonators for high power COIL systems. The advanced diagnostics and computational modeling are also mentioned as very useful tools for critical insight into the laser kinetics and fluid dynamics, supporting thus the COIL research. The recent progress in the COIL development moves this laser closer to the application projects that are also briefly presented.

“…However, the beam is attenuated by a number of environmental factors which can result in jittering and distortion of the beam. The consequence of this is that in certain environmental situations the HEL beam may diverge from its target or not deliver sufficient power to cause thermal disruption [7,8].…”

Directed energy weapons provide a number of useful functions for the modern fighting force, and hence it is useful to produce a framework in which such a weapon's performance can be predicted. Towards this objective this paper introduces a new stochastic model to determine the number of targets defeated by a directed energy weapon over a given time interval. The key to this is to introduce a general queueing model, where arrivals are modelled by a renewal process, and the service time of a target being affected by the weapon is related to its probability of defeat. The queue is assumed to have an infinite capacity, and it is shown how the waiting time of detected threats can be modelled by an auxiliary delay process. A random variable counting the number of targets processed by the queue is then defined. Several functions constructed from this random variable will be investigated in order to identify a suitable metric for assessing performance. In order to facilitate this an example where a high energy laser is used for threat defeat is examined to investigate the utility of the identified performance metrics. As will become apparent, the modelling framework has considerable utility due to the fact that it can be used for performance prediction of any weapon system where an arrival process of threats and corresponding probability of defeat can be specified.
