Maximum Likelihood Registration for Active Sensors on Multiple Airborne Platforms in WGS-84
It is the precondition of coordinated air combat to register the active sensors onboard multiple moving airborne platforms.Firstly, a biased measurement model based on WGS-84 (world geodetic system-84) coordinate system is constructed, and then the Maximum Likelihood Registration (MLR) algorithm is extended to active sensor registration on multiple moving airborne platforms in WGS-84.By using the chain rule for composite function derivation, the Jacobian matrix of sensor measurements with respect to target states is derived, which is critical for MLR application.Theoretic analysis and simulation results show that the method can realize sensor registration with the registration error approaching the Cramer-Rao Lower Bound(CRLB).
