Abstract

First and second passive sensors (14,16), which may be mounted on different earth orbiting satellites, provide relative azimuth and elevation coordinates to sensed objects (A,B,C) such as hostile missiles. Minimum and maximum possible ranges to the objects (A,B,C) along lines-of-sight (18a,18b,18c) from the first sensor (14) are predetermined, and used to calculate "range lines"
(24,26,28) which are coincident with the lines-of-sight (18a,18b,18c) and extend from the respective minimum to maximum ranges respectively. The range lines (24,26,28) are transformed into the field of view of the second sensor (16), and matched to the azimuth and elevation coordinates of the respective objects (A,B,C) using a basic feasible solution (greedy) or global optimization algorithm. The approximate points of intersection of lines-of-sight (20a,20b,20c) from the second sensor (16) to the objects (A,B,C) and matched range lines (24,26,28) are calculated, and transformed into coordinates relative to a reference point (10) such as the center of the earth (12). The calculations for the individual objects (A,B,C) may be performed simultaneously using parallel processors (44a,44b,44c) in a single instruction stream - multiple data stream (SIMD) or similar computing arrangement (40).
