These codes have a more complicated signal structure making it more difficult to be intercepted and detected by a hostile
intercept receiver.
This book/CD-ROM package can serve as a textbook for senior undergraduate students in electrical engineering and physics, and reference for practitioners in radar and digital
intercept receiver design.
The Prophet
intercept receiver can be configured to operate as a manpack system in support of forced entry airborne or air assault operations, and when vehicle-mounted, can operate on the move (OTM) in support of offensive and defensive operations.
This operates with the passive TSQ-112 Tacelis Sigint equipment consisting of the ULK-17
intercept receiver and a UYK-19 computer.
However, a practical
intercept receiver is required to provide digital data to a display system or signal processor.
A radar achieves bandwidth advantage over an
intercept receiver, because the radar can match its receiver and its processing to its own signal, whereas the
intercept receiver must accept a wide range of signals and must typically make detailed parametric measurements to identify the type of signal it is receiving.
* LIDAR
Intercept Receiver: Recent foreign sales of Canadian and Swedish laser detection and ranging (LIDAR) bathymetry and ASW systems have raised the need for LIDAR transmission detection.
The look-through mode is generally interlaced with the transmission mode so that the
intercept receiver can operate at full sensitivity during the short periods in which the jammer is silent.
Racal Radio/Racal Radar Defence Systems (UK): For battlefield SIGINT applications, Racal Radio offers a range of systems which includes the 2- to 1,000-MHz RA1796
intercept receiver, the 1.6- to 1,000-MHz MA1122 direction-finding processing and display unit, the 1- to 30-MHz RDF3210 interferometer direction-finder, the 20- to 1,000-MHz FARS acquisition receiver and the 1- to 1,000-MHz light-vehicle-mounted Seeker III combined communications-band intercept and direction-finding system.
Taking these in the order given, Denmark's Dansk Radio SA produces the 0.5-to 18-GHz RX4010
intercept receiver, while Per Udsen is marketing an airborne self-protection system centered around its F-16-oriented Pylon Integrated Dispenser Station (PIDS) and Electronic Combat Integrated Pylon System (ECIPS).
First, the signal must be present within the detection band of the
intercept receiver; second, the signal-to-noise ratio must be adequate for the detection process to be successful.
