Adapting electronic warfare to radar waveforms

Modern methods of electronic warfare must consider that many sources of information are available to sensor systems. Situation awareness is created in a network of sensors and human operators by a process analysed in this paper. Each step in this process suggests a method of electronic warfare. The analysis is based on a division of radars into two basic groups, surveillance and tracking radars, depending on the amount of information received. Human knowledge is used in surveillance systems and this makes information flooding an effective method of attack. Distraction with noise and chaff and deception with decoys may be preferred in other cases. The conclusions have been tested in trials performed with the Swedish air surveillance system during staff training.
