Abstract: The present invention addresses the resolving of the problems associated with the passive location of targets in TOA (Time of Arrival) or TDOA (Time Difference of Arrivals) mode. The method of passively locating a target in TOA or TDOA mode implements a meshing (subdivision) into blocks of the space in which the location area is situated. The set of the blocks that form this mesh is analyzed iteratively. On each iteration, each block of interest is subdivided into smaller identical subblocks. A block of interest is, according to the invention, a block including at least one point belonging to the location area being sought for which the shape is to be determined. The iterative process is stopped when the size of the subblocks obtained on the current iteration corresponds to the desired resolution. The invention applies in particular to the 2D or 3D location systems that include TOA and TDOA modes or mixed modes.

Abstract: A signal processing method performs operations of coherent processing making it possible notably to purge the useful signal of the spurious signals (in particular the reference signal and its multiple reflections), to regenerate the transmission signal and to perform a coherent integration of the signal received by computing the cross-ambiguity between the signal received and the regenerated transmission signal. It also performs operations of non-coherent processing making it possible in particular to carry out extraction and Doppler distance purification operations making it possible to form blips and to eliminate the spurious blips present among the blips formed. The method applies notably to passive radars operating on non-cooperating opportunity transmissions, such as FM transmissions intended for the public.

Abstract: According to one aspect of the invention, a remanufacturing method of a liquid container forms an inlet in a downstream wall surface of a second chamber, which defines part of a bottom face of the liquid container. In the state of closing a liquid feeder and opening an air open structure, the remanufacturing method injects a liquid through the inlet to fill the second chamber with the liquid. In the state of opening the liquid feeder and closing the air open structure, the remanufacturing method injects the liquid through the inlet to fill a space from the second chamber to the liquid feeder with the liquid. The remanufacturing process seals the inlet after completion of the injection of the liquid. This arrangement enables the liquid to be efficiently refilled into the liquid container without damaging the functions of the liquid container.
