Abstract
Methods and apparatus for inspecting an underwater vehicle. In embodiments, a system receives a SAR image for at least a portion of an exterior surface of an underwater vehicle and performs CCD processing to compare a baseline SAS image for the underwater vehicle with the received SAR image of the underwater vehicle to generate a CCD output corresponding to a measure of similarity of the baseline SAS image and the received SAS image. The system determines whether there was tampering of the underwater vehicle based on the measure of similarity.
Claims20
A method, comprising
- receiving a SAS image for at least a portion of an exterior surface of an underwater vehicle;
- performing coherent change detection processing to compare a baseline SAS image for the underwater vehicle with the received SAS image of the underwater vehicle to generate a CCD output corresponding to a measure of similarity of the baseline SAS image and the received SAS image;
- and
- determining whether there was tampering of the underwater vehicle based on the measure of similarity.
An apparatus, comprising:
- a processor and memory configured to:
- receive a SAS image for at least a portion of an exterior surface of an underwater vehicle;
- perform coherent change detection processing to compare a baseline SAS image for the underwater vehicle with the received SAS image of the underwater vehicle to generate a CCD output corresponding to a measure of similarity of the baseline SAS image and the received SAS image;
- and
- determine whether there was tampering of the underwater vehicle based on the measure of similarity.
An article comprising a non-transitory computer readable medium having stored instructions that enable a machine to:
- receive a SAS image for at least a portion of an exterior surface of an underwater vehicle;
- perform coherent change detection processing to compare a baseline SAS image for the underwater vehicle with the received SAS image of the underwater vehicle to generate a CCD output corresponding to a measure of similarity of the baseline SAS image and the received SAS image;
- and
- determine whether there was tampering of the underwater vehicle based on the measure of similarity.
