Radar

 

Principles of airborne Radar is the signal analysis of the reflection of radio waves in different frequencies from the surface. The radio waves can penetrate clouds and cover large areas economically for surface analysis.

 

 

 

 

Airborne RADAR is an active imaging technology that operates in the microwave portion of the electromagnetic spectrum by emitting short pulses of microwave energy and recording the reflection from a given area on the ground. The resolution of a RADAR imaging system in the cross-track direction (i.e. perpendicular to the flight path) is determined by the pulse duration (shorter pulse = higher across-track resolution), while the resolution of the RADAR in the azimuth direction (parallel to flight direction) is determined by the length of the antenna aperture (i.e. longer aperture = higher azimuth resolution).
