| 73 | Pairwise grouping of joint sparsity models for sensing array processing | US13780450 | 2013-02-28 | US09239388B2 | 2016-01-19 | Petros T Boufounos |
| A scene is reconstructed by transmitting pulses into a scene from an array of transmitters so that only one pulse is transmitted by one transmitter at any one time. The one pulse is reflection by the scene and received as a set of signals. Each signal is sampled and decomposed to produce frequency coefficients stacked in a set of linear systems modeling a reflectivity of the scene. Then, a reconstruction method is applied to the set of linear systems. The reconstruction method solves each linear system separately to obtain corresponding solutions, which are shared and combined to reconstruct the scene. | ||||||

| 80 | Method for Global Acoustic Positioning of a Marine or Submarine Target | US13452373 | 2012-04-20 | US20130128700A1 | 2013-05-23 | Sebastien PENNEC; Pierre-Yves MORVAN |
| A method for the global acoustic positioning of the USBL or SBL type of a marine or submarine target is more accurate than the method used by known USBL or SBL systems, while applying a network of sensors having the same material dimensions as those of these known systems. The method makes use of the movements of the network of sensors to apply principles of the processings by synthetic antenna. The principle of the synthetic antenna transposed to the present problem consists in using the signals received by the hydrophones of a physical antenna placed on a moveable platform at K different moments in succession, and therefore at K locations in succession in order to provide an estimate of the position of the beacon by virtue of an antenna of virtually greater dimensions. | ||||||
