A stochastic vulnerability analysis method for armored vehicles with active protection systems (APS)

Abstract

A stochastic vulnerability analysis method for armored vehicles with APS was proposed. A two-processes threat-target interaction, including an interception process and a damage process, replaced the one-process of threat-target interaction in the traditional vulnerability method. Depending on the vulnerability results of the incoming threat, various residues-after-interception because of detection or interception failure, deflection, explosion and/or decomposition of the threat and collateral damage was generated and treated as input in the damage process. After randomization of the interception point, the residual penetrator deflection, warhead performance, behind armor debris, and component vulnerability characterization, a stochastic vulnerability analysis was performed. The stochastic model could provide damage states of all the critical components of interest, more practical and informative compared to the expected model.

Guarantees of Minimum Performance Levels With Directed Energy Weapons

“…Recent work at Defence Science and Technology Group (DSTG) has not only examined the performance analysis of single DEW effectors [13], but has explored their application to active protection systems (APS). An APS permits a series of armoured fighting vehicles (AFVs) to be equipped with an automatic threat detection and defeat system [14,15]. Studies at DSTG have investigated the concept of collaboration between AFVs equipped with APS which utilise DEWs [16][17][18][19].…”

Armoured Fighting Vehicle Team Performance Prediction against Missile Attacks with Directed Energy Weapons

“…Performance prediction of collaborative active defence systems for a team of armoured fighting vehicles (AFV) is of significant importance to defence forces investing in modern technology. In particular, active protection systems (APS) are being examined in terms of their military utility [1]. The concept of collaboration with such systems, especially when coupled with emerging disruptive technology for threat defeat, is of considerable interest to Defence Science and Technology Group.…”
