Time is an important attribute of an intercepted RF signal and has been used extensively for locating an emitter using multiple geographically distributed Sensors. Sensors can be built as a simple, covert interception system with no Direction Finding (DF) capability or as a high-end ESM System with high accuracy DF and Radar Finger Printing capability, supplying azimuth information and other Radar intra-pulse and inter-pulse parameters. The common thread running across the Sensors is the time stamping of the intercepted signals against a synchronized global clock located at each Sensor. The accuracy with which the Global Clock needs to be synchronized across geographically distributed Sensors may range from a few nanoseconds to tens of nanoseconds. This paper brings out the configuration of a real-time, Time-triggered distributed Radar Sensors Network (TTN). The generation of the accurate, synchronized Global Clock, network management and achieved practical results have been brought out.
