As SAR [synthetic aperture radar] is a coherent imaging system two forms of change detection may be considered, namely incoherent and coherent change detection. Incoherent change detection identifies changes in the mean backscatter power of a scene typically via an average intensity ratio change statistic. Coherent change detection on the other hand, identifies changes in both the amplitude and phase of the transduced imagery using the sample coherence change statistic. 3, record 1, English, - coherent%20change%20detection

Record number: 2, Textual support number: 1 OBS
Radar terminology refers to individuals "looks" as groups of signal samples in a SAR processor that splits the full synthetic aperture into several sub-apertures, each representing an independant "look" of the identical scene. The resulting image formed by incoherent summing of these "looks" is characterized by reduced speckle and degraded spatial resolution. 3, record 2, English, - multiple%20looks

La terminologie radar définit les visées individuelles comme des paquets d'échantillons de signal dans un processeur SAR qui divisent l'ouverture synthétique totale en plusieurs sous-ouvertures, chacune représentant une visée individuelle de la même scène. L'image résultante est formée de la somme incohérente de ces visées et se caractérise par un chatoiement réduit et une résolution spatiale dégradée. 3, record 2, French, - vis%C3%A9es%20multiples
