摘　　要：描述了对机动目标跟踪的Kalman滤波方程和空管系统中易于计算的各参数矩阵理论依据及相应的初值,论述了航迹发散的判断依据及抑制算法.结合应用仿真的具体处理算法及步骤,将发散判据和抑制算法应用于空中交通管理系统进行航迹处理.通过项目验证和仿真结果表明,该算法能进行准确的发散判断和有效的抑制处理.Kalman filter equations for maneuvering target tracking are described. Parameter matrix theory for the simplified calculation and corresponding initial value are given. Judgment of track divergence and restraining algorithm are discussed. Combined concrete algorithm with measure of application emulation, judgment criterion and restraining algorithm are applied to dispose track in air traffic control system. Emulation result shows that the algorithm can judge accurately track dispersing and restrain divergence effectively.
