摘　　要：对三阶αβγ距离跟踪滤波器进行了研究。在数学建模的基础上,分析不同参数选择对环路性能的影响,推导其等效噪声带宽的计算公式。最后通过Matlab仿真验证了三阶跟踪滤波器的跟踪性能,为工程设计提供了理论依据。The three-order αβγ range tracking filter is studied. Based on the mathematic model, the effect of parameters selection on loop performance is analysed. The formula of the equivalent noise bandwidth is derived. Finally, the tracking performance of range tracking filter is simulated by Matlab. The simulation results provide a theoretical foundation for engineering design.
