WebJan 24, 2024 · Synthetic Aperture Radar (SAR) is a type of remote sensing technology that uses radar to measure the reflection of electromagnetic waves off the surface of the Earth. The basic principle of SAR is to use the motion of a radar antenna to synthesize a large aperture, which allows the radar to achieve high-resolution imaging even from a relatively ... WebJan 20, 2024 · Introduction. Spaceborne synthetic aperture radar (SAR) systems are of considerable interest for snow and glacier monitoring because of the capability to penetrate clouds and because of the high spatial resolution.

The footprint is … WebReal Aperture Radars. Designing and constructing an instrument capable of desirable resolution is not always possible. The following examples (from Lillesand and Kiefer, 1994) illustrate this point. If a wavelength of 5 cm. (0.05 m.) is used, to obtain a resolution of 10 millirads (solving for AL), an antenna would have to be 5 meters long.
