Abstract: The present invention relates to the field of data merging, the term “data” encompassing “observation data”. It relates notably to the data obtained from processing of sonar, radar or optronic signals. The subject of the invention is a method for carrying out the spectral merging and characterization of tracks, each track including the data relating to the evolution over time of the bearing position and of the Doppler frequency of an assumed object. This method includes: a first step of merging the initial tracks which correspond substantially to identical observation directions (azimuths); and a second step of frequency analysis of the tracks resulting from merging the initial tracks and of characterizing the merged tracks whose spectrum takes the form of a harmonic comb characteristic of a single real object. The invention finds for example its application in data merging and echo classification, for narrowband passive sonar applications.

Abstract: An analysis tool provides a call path set for reviewing the security of trusted software components during development. By examining the usage of permissions in programs and libraries within a managed execution environment, potential gaps in the security of trusted components may be identified. A call graph generator creates a permission-sensitive call graph. A call graph analyzer evaluates the permission-sensitive call graph to highlight call paths that may present security risks.
