Patent number: 10234554Abstract: Embodiments described herein simplify the recognition of objects in synthetic aperture radar (SAR) imagery. This may be achieved by processing the image in order to make the shadow caused by the object appear more similar to the object. Alternatively, this may be achieved by processing the image in order to make the layover caused by the object appear more similar to the object. Manipulation of the shadow caused by the object and the layover caused by the object may comprise altering the aspect ratio of the image, and in the case of manipulating the shadow caused by the image, may further comprise transforming the image by reflection or rotation. The aspect ratio of the image may be altered based on information about the image collection geometry, obtained by the SAR.Type: GrantFiled: May 6, 2016Date of Patent: March 19, 2019Assignee: THALES HOLDINGS UK PLCInventor: Malcolm Stevens

Patent number: 9870074Abstract: A control unit is provided with a selector and a plurality of value indicators. One of the value indicators provides a coarse indication of an existing value of an adjustable control quantity. The other value indicators are in another state, distinguishable from the value indicating state. A rotary adjustor provides a manual adjustment facility for a user. Selection of the selector puts the adjustable control quantity in an adjustment mode. In this adjustment mode, rotary actuation of the rotary adjustor allows adjustment of the control quantity. A new value of the control quantity is indicated by a change in the display states of the value indicators.Type: GrantFiled: July 10, 2013Date of Patent: January 16, 2018Assignee: THALES HOLDINGS UK PLCInventor: David Robbins
