A multifrequency SAR study of the Haughton impact structure, Arctic Canada
This study investigates surface roughness properties of the Haughton impact structure in the Canadian Arctic using L-, C-, and X-band SAR. Meteorite impact structures are highly localized geological features, providing impact-exposed subsurfaces of a range of regional stratigraphic columns [1]. The Haughton impact structure exposes a wide range of geological features of central Devon Island including impact-generated products. Thus, geologic mapping of an impact structure can be an effective way to expand our remote predictive mapping throughout the Canadian Arctic.
This article constructs the aviation unit assessment model of flight safety system,proposes to determine the elements of the model in weight by using AHP analysis of the assessment model,and calculates the assessment results based on the corresponding software which developed by this model. Software running results show that the assessment model is scientific and effective.
