Anti-Jamming Transmitter Independent Radar Networks

A transmitter independent receiver network (TIRN) is a network of radar receivers that operates in an area without cooperating with a particular radar transmitter, but rather using transmitters of opportunity (TOA) in order to detect and track airborne, ballistic or surface targets. In this paper a brief vulnerability analysis is given in both the detection/tracking and the communication subsystems of such a network. Electronic Defense (ED) solutions and interference avoidance techniques are given. A TIRN is mostly based in silent (low emission) operation and redundancy techniques. It is briefly described in the introduction. In the following paragraphs dealing with jamming techniques and is discussed, for both the detection and communication subsystems, comparing the results with the classic radar equivalent where applicable. It is finally concluded that such a network less vulnerable than conventional radars in most cases and in some cases even detect possible jammer effectively, at a fraction of the cost of classic radar network.
