- Abstract:
- In practical war case a monocular passive location system usually works as a substitute of an active location system, so it is every important for research on algorithm for passive location system with some initial condition(initial distance and velocity). Based on the three-dimension space movement geometrical model, together with the velocity restraint conditions of target and observer respectively, a model is proposed for algorithm for three-dimension space three-coordinate angle measurement monocular passive location to moving target. The location equations under this model is obtained, the solution existence requirement is discussed, a conclusion is drawn that there may exist two solutions. Consequently, the only solution is achieved upon the supposition that each adjacent three dots in the track are on a line for a target with high velocity. At last, the relevant stimulating system is build, with which location to several track is done. It has shown by computer simulation that the new algorithm is valid for all kind intruding target tracks, and the relative error is less than ±2%.
