5 CONCLUSION
The use of conventional classifiers such as the maximum likelihood (Maxver), which assumes a normal
distribution for the data, may not be adequate for SAR data in general. This suggests the importance to develop
new digital classifiers that take into account distinct statistical distribution for the data, thus allowing for a larger
range of radar data applications.
