METHOD FOR LOCATING A MOBILE OBJECT ON THE BASIS OF BISTATIC DISTANCE AND SPEED MEASUREMENTS OF THE OBJECT USING A MULTISTATIC SYSTEM

摘要

The invention concerns a method for locating a mobile object based on bistatic distance and speed of said object using a multistatic system. The invention is characterized in that it consists in: associating at least two pairs of bistatic distances such that for each pair the ellipsoids determining them have a common focus, in resolving for each pair the intersection of those two ellipses at different altitudes, and in optimizing relative to the altitude variable z the different intersections, and having found the best value of z, in calculating the three-dimensional Cartesian coordinates of said object, and based on the coordinates of the object and at least three bistatic speeds, deducing the direction and the modulus of the true 3D speed sector of the mobile object.
