scatteter (e.g. coller leflectols, or speckle noise in a SAR irnage) is much
less significant than those of lires or hypelbola.
Nurnelical ilnplementation of the Radon tr.ansforur rvas rnade by employing
a fast algolitlul (Hauevelcl ancl I{erman [36]). This algor.ithrn was initially
cleveloped for the fast r-p transfolm which is a cliscretized Radon transfor.m
cleveloped for seisrnic application (Hanevelcl alcl I{erman [36]). The maximurn
slope (maxirnun p-value) usecl in this stucly is f 5.0 (+78.7 in degr.ees).
Two sets of SAR data fi or¡ the Sudbur.y Basin, Ontario, rvere selected for.
the test. The locations of Sudbury Basin and Wekusko Lake test sites ar.e
shown in Figure 6.4. The two SAR data sets include the CCRS's ailbor¡re C-
l¡ancl SAR clata and the ERS-1 C-bancl SAR clata, and images ale r.espectively
shown in Figures 6.5 alcl 6.6. The ERS-1 itrage clata rvas colegister.ed to
ailborne C-banrl SAR irnage.
The Sudbuly Basin is located in easteln Ontario, Canarla, ancl is a northeast
tlencling ellipsoidal geological structure. The SAR irnages provicle a goocl
replesentation of the topoglaphic features ald cettaiu surface geological lineameuts
including faults, dykes, and fractures. The topography irnaged in
the SAR clata ilcludes the lelatively rugged and mountainous Nolth Ralge
of the Sudbury Basil (nolthivest parts of images in Figules 6.5 ancl 6.6),
¿nd the low relief inte¡:ior basin and South Range, An intelesting aspect
of the C-bancl SAR irnagery over this area is that the telrain is uniforrnly
rough lelative to the radar rvavelength (5.6 crn). Thelefole the t,one of the
C-bancl imagery over this area is domilated by the local inciclence angle (i.e.
by topography alone) (Lorvrnan [67]).
