What is the principle of Synthetic Aperture Radar (SAR) in remote sensing?
A. Uses thermal energy emitted by objects
B. Measures reflectance of visible light
C. Uses microwave pulses to create high-resolution images
D. Detects magnetic fields
Answer: Option C
Solution (By Examveda Team)
SAR sends microwave pulses and processes the returned signals to generate detailed images regardless of weather or lighting.Widely used in terrain and deformation studies.This Question Belongs to Geological Engineering >> Remote Sensing And GIS In Geological Engineering
