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

Los problemas de recuperar una portadora de referencia para detección coherente pueden evitarse utilizando detección coherente diferencial de modulación por desplazamiento de fase (MDF) o MDP m-valente (MDPM) a costa de una degradación en la tasa de errores. Además, la detección coherente diferencial evita el uso de bucles de recuperación de portadora coherente y puede tener un tiempo de adquisición o readquisición menor. 1, record 3, Spanish, - detecci%C3%B3n%20coherente%20diferencial
