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 1, English, - C%2Dband%20synthetic%20aperture%20radar

Record number: 2, Textual support number: 1 CONT

Artillery fuzes are tailored to function in the special circumstances of artillery projectiles. The relevant factors are the projectile's initial rapid acceleration, high velocity and usually rapid rotation, which affect both safety and arming requirements and options, and the target may be moving or stationary. Artillery fuzes may be initiated by a timer mechanism, impact or detection of proximity to the target, or a combination of these.  4, record 2, English, - artillery%20fuze

(...), the MTD [Moving Target Detection] principle involves dividing up the entire radar coverage area into small range-azimuth cells-(...) called ’coherent processing intervals’(CPI). 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 6, 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 6, French, - intervalle%20de%20traitement%20coh%C3%A9rent
