摘要
(US9140786) A method for detecting an oil mass covered by ice includes collecting radiometric data different frequencies, corresponding to respective different depths into the ice, using at least one airborne platform moved about a search area above the ice so that the radiometric data defines radiometric volumetric data.  The radiometric volumetric data is processed to thereby detect an oil mass covered by the ice.

(US9140786) That which is claimed is: 1.  A method for detecting an oil mass covered by ice comprising: collecting radiometric data at a plurality of different frequencies corresponding to respective different depths into the ice, using an electromagnetic (EM) radiation receiver carried by an airborne platform moved about a search area above the ice so that the radiometric data defines radiometric volumetric data; and   using a processor for processing the radiometric volumetric data, collected at the plurality of different frequencies corresponding to respective different depths into the ice, to define a combined x-y-depth profile representative of a detected oil mass covered by the ice. 2. The method according to claim 1 wherein collecting comprises passively collecting the radiometric volumetric data. 3. The method according to claim 1 further comprising exposing the search area to electromagnetic (EM) radiation so that the collecting comprises actively collecting the radiometric volumetric data. 4. The method according to claim 3 wherein exposing comprises exposing the search area to EM radiation having a frequency resonant with the oil. 5. The method according to claim 3 wherein exposing comprises exposing the search area to EM radiation having a frequency in a range of 8 MHz to 30 MHz. 6. The method according to claim 1 wherein the plurality of different frequencies extend over a range of 30 MHz to 8 GHz. 7. The method according to claim 1 wherein the collecting comprises collecting the radiometric data over a predetermined dwell time for a given location. 8. The method according to claim 1 wherein the processing comprises processing based upon at least one polarization characteristic of the radiometric volumetric data. 9. The method according to claim 1 further comprising collecting the radiometric volumetric data for the search area at a plurality of different times; and wherein the processing further comprises using change detection based upon the plurality of different times for the same search area. 10. The method according to claim 1 wherein the search area comprises a predetermined area around an oil extraction site. 11. The method according to claim 1 wherein the search area comprises a predetermined area around an oil pipeline site. 12. The method according to claim 1 wherein the at least one airborne platform comprises at least one unmanned airborne platform. 13. A method for detecting an oil mass covered by ice using radiometric data collected at a plurality of different frequencies, corresponding to respective different depths into the ice, using an electromagnetic (EM) radiation receiver carried by an airborne platform moved about a search area above the ice so that the radiometric data defines radiometric volumetric data, the method comprising: using a processor for processing the radiometric volumetric data, collected at the plurality of different frequencies corresponding to respective different depths into the ice, to define a combined x-y-depth profile representative of a detected oil mass covered by the ice. 14. The method according to claim 13 wherein the radiometric volumetric data is collected passively. 15. The method according to claim 13 wherein the radiometric volumetric data is actively collected. 16. The method according to claim 13 wherein the plurality of different frequencies extend over a range of 30 MHz to 8 GHz. 17. The method according to claim 13 wherein the processing comprises processing based upon at least one polarization characteristic of the radiometric volumetric data. 18. The method according to claim 13 wherein the radiometric volumetric data for the search area is collected at a plurality of different times; and wherein the processing further comprises using change detection based upon the plurality of different times for the same search area. 19. A system for detecting an oil mass covered by ice comprising: at least one airborne platform comprising an electromagnetic (EM) radiation receiver configured to collect radiometric data at a plurality of different frequencies corresponding to respective different depths into the ice, as the at least one airborne platform moves about a search area above the ice so that the radiometric data defines radiometric volumetric data; and   a processor and a memory coupled thereto configured to process the radiometric volumetric data, collected at the plurality of different frequencies corresponding to respective different depths into the ice, to define a combined x-y-depth profile representative of a detected oil mass covered by the ice. 20. The system according to claim 19 wherein said at least one airborne platform is configured to passively collect the radiometric volumetric data. 21. The system according to claim 19 wherein said at least one airborne platform is configured to expose the search area to electromagnetic (EM) radiation so as to actively collect the radiometric volumetric data. 22. The system according to claim 21 wherein said at least one airborne platform is configured to expose the search area to EM radiation having a frequency resonant with the oil. 23. The system according to claim 22 wherein said at least one airborne platform is configured to expose comprises exposing the search area to EM radiation having a frequency in a range of 8 MHz to 30 MHz. 24. The system according to claim 19 said at least one airborne platform is configured to collect the radiometric volumetric data over a predetermined dwell time for a given location. 25. The system according to claim 19 wherein said processor is configured to process based upon at least one polarization characteristic of the radiometric volumetric data. 26. The system according to claim 19 wherein said at least one airborne platform is configured to collect the radiometric volumetric data for the search area at a plurality of different times; and wherein said processor is configured to process the radiometric volumetric data using change detection based upon the plurality of different times for the same search area.
