Integrated Parameter Identification Model for Targets Maneuvering Linearly at Piecewise Constant Speed under Condition of Passive Direction Finding

For bearing-only tracking of maneuvering targets,the appropriate state variants and parameters are chosen,and the first-order sensitivity functions of parameters are analyzed.Based on this analysis,an integrated parameter identification model and the algorithm for targets maneuvering linearly at piecewise constant speed are given.Simulation results show that the presented model and algorithm adapt well to motion parameter identification for the maneuvering target described here.
