Low Probability of Intercept (LPI)
, 1998 Low 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.

On sensitivity analysis of low probability of intercept (LPI) capability
MILCOM 2005 - 2005 IEEE Military Communications Conference, 2005 For 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.

Low probability of intercept (LPI) techniques and implementations for radar systems
Proceedings of the 1988 IEEE National Radar Conference, 2003 After 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

Waveform design for MIMO radar with low probability of intercept (LPI) property
2011 IEEE International Symposium on Antennas and Propagation (APSURSI), 2011 A joint waveform and array signal processing approach is proposed to minimize MIMO radar antenna radiation power for best low probability of intercept (LPI) property in pre-selected directions and to achieve near-optimum target detection simultaneously. Some simulation results are presented.

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,
