1
Q
Kepanjangan SAR
A
Synthetic Aperture Radar
2
Q
What is SAR
A
Active sensor transmitting the electromagnetic waves in P-Ka band. So, the signals can penetrate clouds, enabling measurements under all conditions.
3
Q
SAR uses ….. technique to ….
A
Signal processing, to improve the resolution
4
Q
How to operate SAR? What is its characteristic?
A
Setting antenna pointing to the side of airborne platforms.
The geometry is different from photogrammetry and optical sensor, but same in range-azimuth coordinates
5
Q
The polarization information of SAR enables ………, such as …. , …. , … of object
A
The detection of physical characteristics of the object
6
Q
What can we get from information recorded by SAR? What is it for?
A
Coherence and interferometry for deformation and stability
