An analysis of the modern technology employed in Electrical Warfare systems is carried out. Electronic and optical techniques presently used in the detection, localization, processing and identification of signals, linked with active and passive countermeasures and countercountermeasures, are analyzed. "Seal-world" designs and configurations are discussed with respect to effectiveness, reliability and designs and operational trade-offs. Topics are divided according the modern classification of Electronic Warfare, covering confusion reflectors, masking and deceiver jammers, intercept receivers as well as the new field of Electro-Optical Electronic Warfare. special characteristics inherent to the Surface Navy are pointed out. In the Appendices, the experiment of a circuit devised to be useful in signal recognition is described, and a list of missiles with electronic and guidance characteristics is presented.
