LPI waveform design using chirplet graphs

OCEANS 2015 - MTS/IEEE Washington, 2015
The Low Probability of Intercept (LPI) signals are of great interest in underwater acoustics. LPI signals are designed such that their presence is difficult to detect, hence taking countermeasures against them are less likely. The traditional method of LPI waveform design is to spread the signal energy in time and/or frequency thus making it ...

Performance bounds for LPI communications

Conference Proceedings on Tactical Communications, Vol.1., 2002
Evaluation of the theoretical lower bound on signal-to-noise ratio for a spread spectrum system is provided. The bound is based on Shannon's sphere packing bound and is evaluated for a finite probability of error and coding complexity. Coding delay, which is the time from when the first information bit enters the encoder to when the first information ...

Stochastische Programmierung unter LPI-Bedingungen

1976
Die Fachliteratur, die den Problemen der stochastischen Programmierung gewidmet ist, ist besonders im Bereich der linearen Programmierung sehr umfangreich. Leider nicht fur den Fall stochastischer Modelle, in denen die Verteilung gewisser Zufallsvariablen nur teilweise bekannt ist.

Muti-Channel Digital LPI Signal Detector

2006 CIE International Conference on Radar, 2006
The theory of LPI radar signal interception is introduced and a method using multi-channel digital deramping is discussed in detail for FMCW signals. Many simulation experiments on the method have been done in several possible situations, and on the basis of them, the influences of mismatch factor and unsynchronized phase on the detection performance ...

LPI Radar: Fact or Fiction

IEEE Aerospace and Electronic Systems Magazine, 2006
LPI radar is a system that consists of a radar and ES system. Its performance depends on both components. An LPI performance factor is derived and applied to several examples. Operational LPI radars are described. A digital LPI radar detector is described and test results presented.

Preliminary Talk and LPI Tasks

2017
This chapter provides an introduction and overview of interview tasks and the preassessment interaction that is considered the preliminary or warm-up to the actual interview tasks. It features two contrastive warm-up excerpts that potentially influence the stance of the candidate to the subsequent tasks.

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.
