Abstract: The invention relates to a data processing method for a multistatic radar system comprising a plurality of transmitters and receivers, each receiver being associated with one or more transmitters so as to form one or more bistatic bases. According to the invention, the method involves producing and sustaining multi-receiver Cartesian tracks from bistatic blips produced by the various receivers, and comprises: a first step in which mono-receiver Cartesian tracks are produced and sustained, each mono-receiver track consisting of blips formed by a given receiver; and a second step in which multi-receiver Cartesian tracks are produced and sustained, each multi-receiver track being constituted by merging the mono-receiver tracks together and with bistatic blips which have not been associated with a mono-receiver track. The produced tracks are transmitted together with the attributes thereof to processing means operating upstream from the method.

Abstract: The invention consists of a method that makes it possible to produce an association of bistatic blips, formed by the different bistatic bases of a multistatic radar system comprising a plurality of transmitters and receivers remote from one another, this association making it possible to transmit to the tracking means only bistatic blips that probably correspond to one and the same target so as to facilitate the work of the tracking means. The association of blips that is produced takes into account the parameters defining, in three dimensions, the bistatic measurements (distance and speed), as well as the azimuth measurement, relating to the corresponding target.

Abstract: A method is disclosed for merging detection information produced by various sensors of a detection system formed by a passive radar system including various bistatic bases and by an external sensor. The method includes two processing phases. During the first phase, for each bistatic base of the passive radar bistatic plots produced by that bistatic base are first merged with bistatic plots produced on the basis of plots transmitted by the external sensor and projected into the bistatic base concerned. Then, by associating all the bistatic bases, bistatic tracking is applied to the merged bistatic plots and unmerged bistatic plots coming from the external sensor. During the second phase a cartesian tracking is generated on the basis of bistatic plots that contributed to forming the bistatic tracks.

Abstract: The present invention relates to the general field of radar tracking applied to multi-static radar systems. It consists of a method for coherently merging the individual tracks generated from the various bistatic bases that make up the system so as to generate and maintain global tracks so that an object detected by a single bistatic base is represented by the corresponding track and an object detected by a number of bistatic bases and giving rise to the creation of a number of individual tracks is represented only by a single global track.

Abstract: The present invention relates to populations of trangenic plants encompassing a substantial part of all codogenic gene segments of a donor organism, and to biological material derived therefrom, plasmid collections and populations of transformed host organisms with which plants can be transformed in a suitable manner. There are also described methods for generating the plants and the material, and the use of the plants and of the material for functional studies. The codogenic gene segments are integrated into the genome of the plants. For example, there are described a population of plants of the species Arabidopsis thaliana into whose genome the codogenic gene segments from Saccharomyces cerevisiae are integrated, and their morphological analysis under normal conditions and stress conditions.

Abstract: The present invention describes genes and methods for the isolation of genes which encode gene products which, if not present, lead to a greatly delayed growth and/or complete standstill of growth of Arabidopsis thaliana at the seedling level. The invention describes the use of these genes and gene products encoded by them for the discovery of novel herbicides. In addition, the present invention describes the use of the genes and gene products identified herein for the generation of plants which are resistant to herbicides. The present invention also relates to a method for identifying herbicidally active substances, to substances identified by this method and to their use as herbicides. The invention furthermore relates to nucleic acid constructs, vectors, organisms comprising the nucleic acid constructs and/or vectors, specifically transgenic plants comprising the nucleic acid constructs and/or vectors.
