Doppler weather radar. For many years radar has been used to provide information about the intensity and extent of rain and other forms of precipitation.... A major improvement in the capability of weather radar came about when engineers developed new radars that could measure the Doppler frequency shift in addition to the magnitude of the echo signal reflected from precipitation. The Doppler frequency shift is important because it is related to the radial velocity of the precipitation blown by wind(the component of the wind moving either toward or away from the radar installation). Since tornadoes, mesocyclones(which spawn tornadoes), hurricanes, and other hazardous weather phenomena tend to rotate, measurement of the radial wind speed as a function of viewing angle will identify rotating weather patterns.  3, record 1, English, - Doppler%20weather%20radar

synthetic aperture radar; SAR :[A] synthetic aperture radar(SAR) is a side-looking imaging radar usually operating on either an aircraft or a spacecraft. The radar transmits a series of short, coherent pulses to the ground producing a footprint whose size is inversely proportional to the antenna size, its aperture. Because the antenna size is generally small, the footprint is large and any particular target is illuminated by several hundred radar pulses. Intensive signal processing involving the detection of small Doppler shifts in the reflected signals from targets to the moving radar produces a high resolution image that is equivalent to one that would have been collected by a radar with a much larger aperture.  4, record 3, English, - C%2Dband%20synthetic%20aperture%20radar

The laser(or lidar) velocimeter [lidar=light radar] operates in a fashion entirely analogous to that of the airborne Doppler weather radars likely soon to be available for detecting turbulence in storm cells. As with radars, the device detects air movements by observing the motion of particles suspended in the air and carried with it. The only significant difference is that a beam of coherent infrared radiation is used to scan ahead of the aircraft, instead of a beam(or series of pulses) of radio energy in the considerably longer-wavelength microwave band. The frequency of the back-scattered echoes or reflections undergoes Doppler shift detection by standard heterodyning techniques, which involve comparing the frequency of the reflected illumination with that of the original laser beam. Any reflecting object or material which has motion relative to the transmitter/receiver will cause a detectable shift in frequency, which can be isolated from the transmitter's own proper motion(over the ground) and thus yield a precise indication of the speed at which the air is moving several hundred metres in front of the aircraft. From this data, it is easy to compute what the air speed of the aircraft will be when it reaches that particular patch of air in a few seconds’ time [and hence detect possible turbulence ahead].  2, record 30, English, - laser%20velocimeter

Eight pulses generated at a constant repetition frequency are assigned to each cell, and each return is subjected to Doppler filtering over a range of velocity values. The particular feature of MTD is its ability to measure the density of clutter and to detect the sudden presence of an additional element-such as an aircraft moving into a particular cell-even though it may have zero relative velocity on account of its tangential track.  1, record 32, English, - coherent%20processing%20interval

Le principe du MTD [Moving Target Detection] est de diviser la zone couverte par le radar en secteurs définis en distance et en azimut (...) et appelés «intervalles de traitement cohérent» (ITC). A chaque secteur sont affectées huit impulsions émises selon une fréquence de répétition constante et chaque écho est soumis à un filtrage Doppler couvrant toute une gamme de vitesses. La caractéristique essentielle du MTD est son aptitude à mesurer la densité des échos parasites et à y détecter la présence soudaine de tout élément nouveau - tel qu'un aéronef entrant dans un secteur donné - même si sa vitesse relative est nulle du fait que sa trajectoire est tangentielle.  1, record 32, French, - intervalle%20de%20traitement%20coh%C3%A9rent
