48 Chapter 15 SAR Advanced Analysis

49 Light interference on glass plate

50 Geometry of satellite SAR interferometry (Range cross section including two SAR sensors and surface scattering point)

51 Flat Earth phase and topographic phase (range cross section including SAR sensors and surface scattering points) (a) Relationship between incident angle 　 and difference of line of sight distance 　　(solid lines for θa dotted lines for θb ) (b) Interferometric phase caused by different incident angles on 　 a flat surface (Flat Earth phase) (c) Interferometric phase caused by different incident angles on topographic elevation (Topographic phase)

52 Geometry of surface deformation (cross-section including SAR positions and a surface scattering point) (a) Before surface deformation (scattering point Τ1 and T2 is same) (b) After surface deformation (scattering point T1 shifted to T2)

53 Concept of phase unwrapping
(a) Phase BEFORE phase unwrapping (b) Phase AFTER phase unwrapping

54 Example of elevation retrieving using SAR interferometry
Kurume city, Fukuoka Prefecture, Japan, about 15 km2 using JERS-1 SAR data (Satellite data ownership: Ministry of Economy, Trade and Industry (METI) and Japan Aerospace Exploration Agency (JAXA))

55 Example of surface deformation detection using SAR interferometry
Interferogram of southern Hyogo prefecture Earthquake 1995, in Kobe and northern part of Awaji island, Japan, 15 km2 using JERS-1 SAR data (Satellite data ownership: METI and JAXA)

56 Concept of acquiring multiple polarization data

57 Change of polarization caused by the scattering of the target

58 Elliptical polarizations

59 Examples of theoretical polarization signature

60 Examples of polarization signature calculated from PALSAR data

61 Three scattering mechanisms used in Freeman and Durden decomposition
(a) surface scattering (b) double bounce scattering (c) volume scattering

62 Example of Freeman and Durden decomposition method

63 Scattering mechanisms on H-α plane

64 Example of Cloude and Pottier scattering decomposition

65 Example of multi-frequency and polarization images
