The Use of Satellite and Aircraft SAR to Detect and Chart Hazards to Navigation.

Abstract

A total survey of Seasat and SIR-A L-band Synthetic Aperture Radar (SAR) imagery for the presence of bottom-related surface patterns was completed. Aircraft X-band SAR data collected by an APD-10 system was also reviewed. Examples from these three SAR systems are presented which further illustrate the types of bottom-related surface patterns which appear on SAR imagery. A comparison of digital SAR image intensities versus depth data demonstrates the correlation of the SAR surface patterns to bottom features, and when combined with ancillary environmental data, demonstrates the dependence of SAR surface patterns on the ambient environmental conditions. First order hydrodynamic/electromagnetic models are presented which demonstrate how bottom-related surface patterns appear on SAR images.
