METHOD AND PARALLEL PROCESSOR COMPUTING APPARATUS FOR DETERMINING THE THREE-DIMENSIONAL COORDINATES OF OBJECTS USING DATA FROM TWO-DIMENSIONAL SENSORS

摘要

the first and second passive detectors (14, 16), which may be mounted on satellites in different orbits earth, provide coordinates of azimuth and elevation of the detected objects (a, b, c) such as hostile missiles.the minimum and maximum possible distance to objects (a, b, c), along the lines of sight (18a, 18b, 18c) are predetermined from the first detector (14), and are used to calculate "range lines (24, 26, 28) which coincides with the line of sight (18a, 18b, 18c). - extend from respective maximum minimum distance, respectively.distance lines (24, 26, 28) are transformed into the field of view of the second sensor (16) to correspond to the coordinates of azimuth and elevation of the respective objects (a, b, c) by using a basic feasible solution (greedy) or a global optimization algorithm.the approximate intersection of lines of sight (20a, 20b, 20c) from the second detector (16) for the objects (a, b, c) and the pairwise distances (24, 26, 28) are calculated and transformed into coordinates relative to a reference point (10), such as the centre of the review (12).the calculations for the individual objects (a, b, c) may be carried out simultaneously using parallel processors (44a, 44b, 44c) in a series of mono - multidonnu00e9es / training (dmis) or a combination of similar calculation (40).
