Multi-Missile Interception Integrating New Guidance Law and Game Theoretic Resource Management

Abstract

Abstract-Traditional missile interception often focuses on simplified scenarios such as one-to-one or multi-to-one interception. Recently, battlefield situations pose new difficulties for missile defense systems, which make traditional interception systems inefficient. The problems revolve around two aspects: 1) The guidance law insufficiency (traditional forms PN, DGL/1, and DGL/C); and 2) Resource management insufficiency. This paper fuses game theoretic resource management and a noise level related guidance law to existing missile defense system which is called Differential Game Law Type M (DGL/M). Intensive simulations show that this approach demonstrates improvements over existing methods.

Game theoretic target assignment approach in ballistic missile defense

“…This comparison is between game theoretic resource assignment and random assignment. DGL/M [10][11][12] guidance law is applied for both game theoretic resource assignment approach and random assignment approach in this comparison. Each point is the average of 100 Monte Carlo runs under corresponding µ.…”

“…In this paper, we mainly address the execution level and the reader is referred to other companion papers [11] describing the other modules. The information flow under this framework is as follows.…”

“…3) Execution Level (apply different guidance strategies such as PN or Differential Guidance Law type Modification (DGL/M) [10][11][12] to generate specific control commands for antimissiles in the whole time horizon); 4) Interception Evaluation Model (to automatically evaluate executions of missile interception and determine whether new missiles need to be launched or the whole engagement plan should be recalculated); 5) Knowledge and Information Module (to store, provide, and automatically update the knowledge and rules about missile interception); 6) User Interface Module (to provide an easy-to-use graphic interface so that commanders can conveniently choose scenarios from typical situations, modify default scenarios to model new situations, or construct completely new scenarios).…”

“…The problems lie mainly in two aspects: 1) The guidance law problems; and 2) Resource management problems. In this paper, we mainly discuss issues related to the resource management solutions where as updates to the guidance laws are reported in a companion paper [11].…”

Cooperative guidance laws for maneuvering target interceptions

“…It must also ensure that the intercepting trajectories are safe and avoid collateral damages. Several approaches have been developed for cooperative attacks as in Rasmussen et al (2004), Le Menec et al (2011), Wei et al (2008. The differences arise mostly on the means of prediction of target behavior and structure of the guidance laws.…”
