“…Comparison with the results publishedin Ref. 5 shows an impressive improvement of the guaranteed SSKP from 0.4 to 0.7 achieved by the MMAE application. When the 0.9 reliability factor is taken into account, it is essentially a decrease of 150% in the failure rate from 0.5 to 0.2.…”

The terminal phase (end game) of an encounter between an air-to-air missile equipped with an active monopulse radar seeker and an evading ghter aircraft, possibly employing electronic countermeasures in the form of electronic jinking, is addressed. The missile uses a guidance law derived from linear differential game theory, which is implemented by using a multiple-model adaptive estimator (MMAE). The MMAE identi es the evasion strategy of the aircraft, which consists of the combination of evasion maneuver and electronic jinking. An extensive numerical study is used to demonstrate the viability of the concept. In comparison with a previously proposed mixed strategy guidance methodology, the new MMAE-based approach leads to a substantial improvement in the guaranteed single-shot kill probability for the missile.

“…Using a mixed strategy, in which available actions are selected probabilistically, prevents opponents from exploiting predictability during many interpersonal, geopolitical, pursuit-evasion, evolutionary, and sporting competitions (Maynard Smith, 1982;Driver and Humphries, 1988;Shinar et al, 1994;PalaciosHeurta, 2003). Game theory provides insight into these mixedstrategy competitions by outlining normative strategies, that is, specifying the proportion of responses that players should devote to each option once a behavioral equilibrium is established (Nash, 1950;Fundenberg and Tirole, 1991).…”

Game theory outlines optimal response strategies during mixed-strategy competitions. The neural processes involved in choosing individual strategic actions, however, remain poorly understood. Here, we tested whether the superior colliculus (SC), a brain region critical for generating sensory-guided saccades, is also involved in choosing saccades under strategic conditions. Monkeys were free to choose either of two saccade targets as they competed against a computer opponent during the mixed-strategy game "matching pennies." The accuracy with which presaccadic SC activity predicted upcoming choice gradually increased in the time leading up to the saccade. Probing the SC with suprathreshold stimulation demonstrated that these evolving signals were functionally involved in preparing strategic saccades. Finally, subthreshold stimulation of the SC increased the likelihood that contralateral saccades were selected. Together, our results suggest that motor regions of the brain play an active role in choosing strategic actions rather than passively executing those prespecified by upstream executive regions.

A maneuver target interception algorithm based on multiple model adaptive estimator (MMAE) is researched and a modified differential game guidance law is given. The efficiency of this simplified MMAE algorithm lies mainly in the exploitation of the special structure of the evader maneuver command hypothesis space to reduce the number of MMAE elemental filters running in parallel and to realize the reduction of the computational load. To realize the reduction of the miss distance resulting from the estimation delay, the modified differential game guidance law increases the lateral acceleration command for small values of time-to-go of the pursuer to the maximum available value by enhancing the gain of the command. The Monte Carlo simulations are carried out for the homing performance comparison and the results demonstrate the superiority and effective of the proposed methods.
