coherent pulse
1coherent pulse radar — A form of pulse radar in which the radio frequency oscillations in a recurrent pulse bear a constant pulse relation to those of a continuous oscillation. Pulse Doppler radar is of this form. Also called coherent radar. A typical layout of… …

3Pulse-position modulation — is a form of signal modulation in which M message bits are encoded by transmitting asingle pulse in one of 2^M possible time shifts. This is repeated every T seconds, such thatthe transmitted bit rate is M/T bits per second. It is primarily… …
4Pulse-Doppler radar — Pulse Doppler is a radar system capable of not only detecting target location (bearing, range, and altitude), but also measuring its radial velocity (range rate). It uses the Doppler effect to determine the relative velocity of objects; pulses of …
5Coherent anti-Stokes Raman spectroscopy — Coherent anti Stokes Raman spectroscopy, also called Coherent anti Stokes Raman scattering spectroscopy (CARS), is a form of spectroscopy used primarily in chemistry, physics and related fields. It is sensitive to the same vibrational signatures… …
6Coherent diffraction imaging — A diffraction pattern of a gold nanocrystal formed from using a nano area beam of coherent X rays. This reciprocal space diffraction image was taken by Ian Robinson s Group to be used in the reconstruction of a real space coherent x ray… …
7coherent oscillator — An oscillator, in MTI (moving target indicator) radars, providing a coherent reference by which the radio frequency phase of a received pulse may be compared with that of a transmitted pulse …
8noncoherent pulse radar — A form of pulse radar in which the radio frequency oscillates in recurrent pulses but does not bear a constant phase relation to those of a continuous oscillation. Non coherent pulse radar …
9Radar Doppler pulsé — Un radar Doppler pulsé est un radar capable, non seulement de donner le cap, la distance et l altitude d une cible, mais aussi de mesurer sa vitesse radiale (portée vitesse). Pour cela il utilise l effet Doppler. Le retour des impulsions… …
10Quantum amplifier — In physics, the term quantum amplifier may refer to any device, which use some non classical (quantum) effects for amplification of signal. In this sense, the active element of an optical laser can be considered as quantum amplifier.The weak… …
