Coherent radar definition
WebRadar Fundamentals - Faculty - Naval Postgraduate School WebAug 30, 2024 · The radar antenna on board satellites transmits a coherent signal that is backscattered by the Earth surface before being detected by the same antenna. A SAR signal is complex. Each pixel of an image holds intensity and phase information. The intensity depends on the ground roughness, the soil moisture, and the incidence angle.
