Mars Extant Life: What's Next? 2019 (LPI Contrib. No. 2108)
, 2019 Focused on understanding and discussing strategies for exploring for extant life on Mars. We are especially interested in hypotheses that can be tested by means of robotic spacecraft sent to Mars, and hypotheses that can be tested with or without the ...

Development of Indonesian low probability of intercept (LPI) radar system
, 2017 In this paper, the development of a low probability of intercept (LPI) radar based on frequency modulated-continuous wave (FM-CW) technology is described. This LPI radar was mounted on a naval ship.

Spatial Information-Theoretic Optimal LPI Radar Waveform Design
Entropy, 2022 In this paper, the design of low probability of intercept (LPI) radar waveforms considers not only the performance of passive interception systems (PISs), but also radar detection and resolution performance. Waveform design is an important considerations

LPI/LPD Detection Sensitivity Limitations
2014 IEEE Military Communications Conference, 2014LPI/LPD (Low Probability of Intercept/Low Probability of Detection) analyses typically follow the original work of Urkowitz [1] to obtain probability of detection for a specified false alarm rate. Such analyses are based on a uniform time invariant noise background.

An LPI design for secure OFDM systems
MILCOM 2012 - 2012 IEEE Military Communications Conference, 2012Traditional OFDM systems present some embedded features that may be exploited in order to intercept the wireless transmitted signal. However, such a possibility is not accepted in military applications where security is a very important issue. Cyclic prefix is one of the most obvious OFDM parameters that induce cyclostationarity features.

Interception of LPI radar signals
IEEE International Conference on Radar, 2002The interception problem is reviewed, an LPI radar design is examined and the performance of intercept receivers of the future is considered. The receiver needed to intercept LPI signals must respond across a broad band and provide noncoherent integration capabilities over times comparable to the coherent (or noncoherent) integration times used by ...

LPI in pulsed laser space communications
IEEE Journal on Selected Areas in Communications, 1993A basic low-probability of intercept (LPI) study for a pulsed-laser pulse position modulated (PPM) optical link with a colocated direct detection intercepting receiver is presented. The latter is considered to be a form of optical radiometer using continuous threshold testing to detect the presence of the transmitting laser.

LPI waveforms for active sonar?
2004 IEEE Aerospace Conference Proceedings (IEEE Cat. No.04TH8720), 2004The idea of a low probability of intercept (LPI) waveform is that its form is chaotic. It can of course be recalled by the transmitter (platform), and matched to what is received; but to the target it appears only as noise, and consequently the robust target receiver can only detect a rise in energy.
