The first special issue on Radar and Sonar Networks was published by EURASIP Journal on Wireless Communications and Networks in 2010 (Lead Guest Editor: Qilian Liang)
Since then, workshops on Radar and Sonar Networks have been organized in major IEEE conferences such as ICC and Globecom. This special issue continues with further articles in Radar and Sonar Networks which reflects the new advances in this area.
