In NCRS systems examined above, target detection and its parameters measurement are performed based on envelope analysis of reflected oscillations, pick-out by envelope detector. High-frequency pulse filling is used as a carrier frequency that transports information on target to the radar receiver, and as a means of optimal energy storage of a single ...

Coherent multilateration systems
2008 Microwaves, Radar and Remote Sensing Symposium, 2008Passive coherent location systems using ldquotransmitters of opportunityrdquo like radio or TV broadcasters, GSM base stations, satellite communication and GNSS signals has reached a substantial attention in the last years. In this paper the coherent location system, based on bistatic radar principle with multiple non-cooperative transmitters is ...

Analysis of Coherent Multistate Systems
IEEE Transactions on Reliability, 1981The structure and reliability of homogeneous s-coherent multistate systems is studied. Homogeneous systems have two properties: 1) their components can be rearranged internally in any arbitrary way without affecting the mapping of the component states onto the system state; 2) all components, all subsystems composed of them, and the system have the ...

Abstract In Chapter 5, we discussed the establishment of adequate causality, and the management of inadequate causality and accident. Moving up from this local level of the construction of causality, we will next examine the level of the coherence system, a more global cultural device for structuring experience into socially sharable ...

2008 34th European Conference on Optical Communication, 2008
Coherent optical communications were studied extensively in the 1980s; however, their R&D activities have been interrupted for almost 20 years behind the rapid progress in high-capacity WDM systems using EDFAs. In 2005, the demonstration of the digital coherent receiver stimulated a widespread interest in coherent optical communications again.

Coherent Communication Systems
2020In this chapter, we outline the modern coherent communication formats and how they are realized. These coherent communication formats enable long-distance and high-speed transmission. We also discuss the sources of noise in optical communication systems and the relationship between signal to noise, bit error rate, and communication format.

Parallel optical coherence tomography system
Applied Optics, 2007We present the design and procedures for implementing a parallel optical coherence tomography (POCT) imaging system that can be adapted to an endoscopic format. The POCT system consists of a single mode fiber (SMF) array with multiple reduced diameter (15 microm) SMFs in the sample arm with 15 microm center spacing between fibers. The size of the array

Failure profiles of coherent systems
Naval Research Logistics (NRL), 2004AbstractIn this paper we first introduce and study the notion of failure profiles which is based on the concepts of paths and cuts in system reliability. The relationship of failure profiles to two notions of component importance is highlighted, and an expression for the density function of the lifetime of a coherent system, with independent and not ...
