ENVISAT/ASAR may be calibrated using the ERS [European Remote Sensing Satellite] instrument. Two SAR [synthetic aperture radar] images of the same area are required and at least one strong point-like target must be visible in both scenes. The target response should originate from the same stable scatterer. For the technique a very coarse digital elevation model(DEM) of the scene is suitable. The method bases on the very well-known timing parameters and high orbit accuracy of the ERS instrument(5 cm radial and 15 cm along track orbit accuracy).  2, record 3, English, - high%20orbit%20accuracy

CP-1716A Radar Target Data Processor. The CP-1716A Radar Target Data Processor detects AN/SPN-43 primary radar video signals, triggers, and azimuth data, and develops a single digital report for each operating aircraft within the range of the antenna scan. It then transfers the messages to the CP-1716 Track Processor. All operating controls, self-test controls, and indicators are located on the front panel of the equipment. The Radar Target Data Processor consists of 28 types of plug-in circuit cards and a power supply.  3, record 5, English, - radar%20target%20data%20processor

(...), 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 12, 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 12, French, - intervalle%20de%20traitement%20coh%C3%A9rent
