Description
Summary:Analysis on observability of tracking system is the premise and basis of target tracking, only if the observable condition is fulfilled, could the system have correct solution, then the effective tracking of target could be realized. Focus on the observability problem of bearings-only tracking for the target moving in constant acceleration based on multiple (three or more) passive sonar sensors, after the pseudolinear processing is applied on the observable equation as well as the judging theorem of observability for linear system is applied to the tracking system, the observable condition of judging for this system could be obtained, the validity of the conclusion is validated by simulations.
