Witryna10 kwi 2024 · The term coherent (from the Latin cohaerens—consistency) emphasizes the understanding that turbulence, contrary to earlier assumptions, is no longer an example of chaos, but rather a superposition of canonical building blocks of motion with inherent patterns of spatial and temporal consistency.A better understanding of these … WitrynaSynthetic Aperture Radar (SAR) A synthetic aperture radar, or SAR, is a coherent radar system that generates high-resolution remote sensing imagery. Signal processing uses magnitude and phase of the received signals over successive pulses from elements of a synthetic aperture to create an image.
