Abstract.
The paper describes features of interferometric processing of
ALOS\PALSAR multi-temporal radar acquisitions under conditions of changeable
landscapes. Industrial areas of western part of Russian Arctic such as Kovdor
ore mining and processing enterprise and Kolskaya mining company and adjacent territories were selected
as regions of interest. The new method of multi-temporal radar images coregistration
was proposed for accurate frames resampling under conditions of temporal
decorrelation. Maps of ground surface deformations and persistent scatterers
displacements rates were presented. It is concluded that ALOS and ALOS-2 data
can be applied to projects on ecological monitoring of mineral resources
deposits of Kola Peninsula.
Key words:
