Paper Abstract

Because of their proliferation to many regions groups in the world and easy availability by the groups, the infrared (IR) missiles are probably the most dangerous threats for the aircraft platforms. The first generations of the infrared guided missiles which are surface-to-air or air-to-air guided missiles use non-imaging reticle-based seekers. On the other hand, there are some IR countermeasure (IRCM) techniques which may be applied by the aircraft to protect itself from the approaching IR guided missile. One of IRCM techniques for protecting aircraft platforms against IR guided missiles is to use a modulated jamming signal. But to be effective, optimizing the parameters of the jammer modulation is an important issue. The jamming operation may not be successful for protecting the aircraft if the required jamming characteristic is not satisfied. To define the jammer signal modulation characteristic several parameters must be optimized. In the present paper, we consider protection of a helicopter platform against conical-scan reticle based seeker systems. We investigate the optimized value intervals of the jamming parameters via self organizing maps and multidimensional particle swarm optimization methods. The data for investigation is retrieved from a simulator. The corresponding MATLAB-coded simulator includes the model of the guided missile with reticle-based conical-scan seeker, the aircraft model with aircraft radiation and aircraft motion models and jammer system model on the aircraft.
