3 Terms, definitions and abbreviations
3.1 Terms and Definitions
The following terms and definitions apply to this document.
3.1.1 Crustal deformation
The changes in the geometry of the earth's crust occur under the influence of the earth's internal and external forces.
[Source. GB/T 18207.2-2005, 4.4.1]
3.1.2 coseismic deformation
The permanent static displacement of the earth's surface caused by a seismic fault.
3.1.3
The crustal deformation caused between two major earthquakes in the same area.
Note. Interseismic deformation can last for decades, hundreds of years or even thousands of years.
3.1.4
By using the relative motion between the radar and the target, the smaller real antenna aperture is synthesized into a larger equivalent antenna using signal processing methods.
Aperture imaging radar.
[Source. CH/T 3009-2012, 3.1]
3.1.5 single-look complex image; SLC
Complex form of SAR image without multi-look processing.
[Source. GB/T 32874-2016, 3.1.8]
3.1.6 line of sight; LOS
The radar antenna phase center points in the direction of the ground target.
