A game-theoretic analysis of electronic warfare tactics with applications to the World War II era
This thesis considers electronic countermeasures as well thought-out signals sent by the "attacker" to a recipient, the "defender" in order to create uncertainty, and argues that tactics that incorporate the judicious use of bluffing further such uncertainty. I discuss two forms of bluffing, …
