Radar Transponders and Radar Target Enhancers
Journal of Navigation, 1995Radar transponders and radar target enhancers have been in use in a variety of applications for many years. Perhaps the most widely-known applications of radar transponders are in Identification Friend or Foe (IFF) and its civilian counterpart, secondary surveillance radar for air traffic control, and as racons in marine navigation and, most recently ...

2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016
Preliminary results of the comparative analysis of Quantum Radar (QR) based upon quantum entanglement phenomenon and Noise Radar (NR) based upon classical coherence notion and correlation processing of random signals are presented in the paper. It has been shown that the basic idea of entangled multi-photon QR for simultaneous implementing of high ...

Introduction to radar and radar communications
2017Radio detection and ranging (RADAR) is a method of using electromagnetic waves to determine the position of a target. Radar transmits a signal and receives and detects a portion of the signal that is reflected back to the radar. Radar uses this return signal or echo to measure the time it is transmitted to the time it is received to determine the range

Aid Effectiveness: On the Radar and Off the Radar
Development Policy Review, 2017Poverty is a human construct, yet the Euro‐American development assistance programmes that aim to reduce poverty remain a function of systemic problems, profit and politics. Critics argue that widened global income inequality and neoliberalism's ineffectiveness in the Global South can be reflected in recent geopolitical and epistemic tensions.

Radar visibility estimation for radar reflectors
IALA Bulletin, 2007Construction and maintenance of fairways in Finland requires extra caution due to closely-spaced islands, narrow and shallow passages and demanding winter conditions. Therefore, a special authority, the Finnish Maritime Administration (FMA) has been assigned the responsibility of keeping fairways open and safe.

Adaptive radar: evolution to cognitive radar
IEEE International Symposium on Phased Array Systems and Technology, 2003., 2004Summary form only given. Adaptive signal processing is considered to be one of the enabling technologies that will become increasingly dominant in the twenty-first century. Most important, it is well suited for use in the design of phased array radar systems, given the flexibility that such a radar system offers.

Radars multistatiques et radars numériques
Revue de l'Electricité et de l'Electronique, 2006D'une part les operations reseaux centrees (NCW| sur le champ de bataille exigeront des systemes de detection et de pistage interconnectes, menant a la notion "de senseurs distribues" non localises au meme endroit. Cela signifie que les antennes de radar devront explorer simultanement de nombreuses directions differentes et a des frequences RF ...

A radar-to-radar interference prediction model
IEEE 1991 International Symposium on Electromagnetic Compatibility, 2002The radar interference prediction program (RIPP) is described. RIPP is a computer model that predicts interference between radars assuming antenna-to-antenna coupling. The measure of effect that RIPP calculates is the probability of interference (P/sub i/). P/sub i/ is defined as the probability that the interference-to-noise ratio (INR) exceeds the 50%

From radar-77 to radar-97: the international radar directory - at last!
Radar Systems (RADAR 97), 1997Collection of open information on radars of the world for the international radar directory was started twenty years ago at RADAR-77 in London. This resulted in the directory master computer file that contains over 9,800 radars made by about 400 manufacturers in some 30 countries starting in World War II. Publication problems led to focusing on current
