Özet:

Electronic Support Measures is a discipline of electronic warfare. In electronic support measures, receivers must maintain surveillance over the very wide portion of the electromagnetic spectrum in which threat emitters operate. In current receiver technology, it is not possible to have a receiver which is at once both able to discriminate multiple simultaneous emissions and highly sensitive. A common approach is to use a receiver with a relatively narrow bandwidth that sweeps its centre frequency over the threat bandwidth to search for emitters. The sequence and timing of changes in the centre frequency constitute a search strategy or sensor scheduling problem. A good electronic support receiver should observe the threat emitters, usually radars, very soon after it first begins transmitting, so in designing search strategy we would like to ensure that the intercept time is low or the probability of intercept after a specified time is high. In this thesis, we study the search strategies used in electronic support measures receivers. Moreover, a search strategy based on probability of intercept of the threats is proposed. The performances of the search strategies are compared at the end of the thesis.
