A game theory approach to radar ECCM evaluation

Clarke, J. / Subramanian, A.K.

The evaluation of the efficacy of candidate ECCM features in a military radar should be an important part of the design process. In spite of its importance, a well-founded quantified methodology has not hitherto been developed. The essence of the situation to be addressed is one of conflict, and the established theory of games is known to be applicable. Of particular relevance is the capability of the theory to accommodate uncertainty. Accordingly, the use of Game Theory is promoted here for ECCM analysis and design. Some if the elements of the theory have been introduced and their application to ECCM evaluation explained. The utility of this approach has been demonstrated by examples. It can be seen that the detailed choices available in ECCM and ECM along with their effectiveness is very important, and indeed this can be linked in to the value of both Intelligence and Secrecy. The Game Theory approach is equally applicable to ECM design. The theory can also accommodate degrees of co-operation as well as competition and confrontation, for example in a limited conflict both sides may recognise a need not to interfere with certain air traffic or navigation services, this has not been addressed here. The employment of Game Theory will fulfil a long felt need in the Radar ECCM Design field.
