On sensitivity analysis of low probability of intercept (LPI) capability
MILCOM 2005 - 2005 IEEE Military Communications Conference, 2005For operational purposes, the low probability of intercept (LPI) capability of a waveform is usually quantified by the area of being intercepted by a detector. The radius of a circular area equivalent to the vulnerable area, the Circular equivalent vulnerable radius (CEVR), is used to indicate the vulnerability.

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
