Patent number: 11460564Abstract: A method for calibrating an acoustic antenna including elementary transducers distributed over an antenna row or plane, about a reference transducer, the antenna defining a main axis, passing through the reference transducer, and perpendicular to the antenna row or plane, the method including: measuring signals generated by elementary transducers in response to a calibration acoustic wave from a calibration source; on the basis of these measurements, determining a temporal phase shift of the signal respectively generated by each elementary transducer; reiterating the above steps in such a way that, in at least one iteration, the position of the calibration source may be considered to be centered on the main axis; and estimating a phase shift of each elementary transducer with respect to the reference transducer.Type: GrantFiled: July 7, 2020Date of Patent: October 4, 2022Assignee: Commissariat A L'Energie Atomique et aux Energies AlternativesInventors: Regis Perrier, Van-Tri Nguyen

Patent number: 9135716Abstract: Method for estimating the movement of an observation instrument on-board a vehicle flying over a celestial body, the instrument including at least two strips with different lines of sight, each strip realizing the acquisition of successive image lines making up a composite image, parts of the composite images representing substantially a same scene of the celestial body. The estimated movement is determined by optimization of an image similarity function that associates, to a given movement hypothesis, a similarity between values of matched pixels of at least a pair of composite images. The method includes, for each movement hypothesis considered during the optimization: determining, for the at least one pair of composite images, at least one spatio-temporal transformation using the considered movement hypothesis and a geometric model of the observation instrument, and matching the pixels of the at least one pair of composite images using the at least one spatio-temporal transformation.Type: GrantFiled: November 12, 2010Date of Patent: September 15, 2015Assignee: AIRBUS DEFENCE AND SPACE SASInventors: Régis Perrier, Mathias Ortner, Elise Arnaud, Peter Sturm
