MILCOM 2013 - 2013 IEEE Military Communications Conference, 2013
Using radiometric detection, the detection threshold for a wideband radiometer (WR) to detect bursty signals e.g., transmission with duty cycle in frequency hopped systems is discussed in the paper. For this detector, the detection threshold is characterized by the probabilities of false alarm and detection, hopping bandwidth, duration of transmission,

Low probability of intercept (LPI) techniques and implementations for radar systems
Proceedings of the 1988 IEEE National Radar Conference, 2003After a brief overview of optimal low-probability of intercept (LPI) radar design criteria, it is shown that for a given radar signal code length, many more codes are available by using higher-order Galois fields; that is, polyphase coding will supply the required diversity. Various aspects of polyphase coding are described because Doppler compensation

Low Probability of Intercept (LPI)
1998Low probability of intercept (LPI) is the term used for there being a low probability that a radar's emissions will be usefully detected by an intercept receiver in another aircraft or on the ground. For the air battle of the future, LPI is essential. In conventional aircraft the most important need for LPI is to avoid electronic countermeasures.
