Description: 瞬时频率的解释和瞬时频率估计算法的介绍,回顾目前存在的一些瞬时频率估计算法以及作者提出的新的算法-This paper, which addresses the important issue of estimating
the instantaneous frequency (IF) of a signal, is a sequel to the
paper which appears in this issue, and dealt with the concepts
relating to the IF. In this paper the concept of IF is extended to
be able to cope with discrete time signals. The specific problem explored is that of estimating the IF of frequency modulated
(FM) discrete-time signals imbedded in Gaussian noise. There are many well established methods for estimating the IF-these methods include differentiation of the phase and smoothing thereof adaptive frequency estimation techniques such as the phase locked loop (PLL), and extraction of the peak from time-varying spectral
representations. More recently methods based on a modeling of the signal phase as a polynomial have been introduced. All of these methods are reviewed, and their performances are compared on both simulated and real data. Guidelines are
given as to which estimationmethodshould be used for Platform: |

Description: 针对传统线性调频(LFM)信号参数估计算法中复杂的搜索和计算问题,提出了一种不需要参数搜索的快速
LFM信号参数估计算法。该算法先用希尔伯特变换估计LFM信号瞬时相位,再用二次相位函数拟合LFM信号瞬
时相位从而得到初始频率和调频斜率的估计-The traditional linear frequency modulation (LFM) signal parameter estimation algorithms and computational complexity of the search problem, we propose a fast search without LFM signal parameter estimation algorithm. The algorithm first estimated with the Hilbert transform of LFM signal instantaneous phase, and then the second phase of LFM signal instantaneous phase function fitting to obtain the initial estimates of the frequency and chirp rate Platform: |
