摘要 离散多项式相位变换分析法是线性频率调制(LFM)信号参数估计方法中的常用方法,但其缺点是参数估计范围较小,不利于工程实现。文中以线性迭代预测(ILP)方法为基础,介绍了ILP方法的基本原理,提出了一种LFM信号参数估计范围的改进方法,给出了LFM信号参数估计范围改进的基本思想和实现步骤,该方法在保证估计精度的前提下能大大提高估计范围。最后仿真验证了该方法的有效性。 In algorithm for estimation of LFM signal parameter,the Discrete Polynomial Phase Transform(DPT) method is a common method.However,the method is not suitable for engineering application due to limited range of signal parameter esimation.Therefore,based on the method of Iterative Linear Prediction(ILP),modified method of range of signal parameter estimation is proposed.On the condition of ensuring estimation precision,this method can greatly improve the range of estimation.First,the theory of ILP measurement...
