Abstract

An algorithm for combined estimating the frequency and its rate of variation of a linear frequency modulated signal by a sample of increasing size is proposed. The proposed algorithm admits recursive calculation of estimates that take into account the presence of time correlation of errors of the original difference-phase measurements. The solution method is distinct in computational efficiency, and the resulting estimate tends to optimal one in the dispersion minimum as the input signal/noise ratio increases.

通过增加大小的样本估计 LFM 信号的频率参数

摘要

提出了一种通过增大样本对线性调频信号的频率及其变化率进行组合估计的算法。所提出的算法允许估计的递归计算，考虑到原始差相位测量的误差的时间相关性的存在。该求解方法在计算效率上是不同的，随着输入信噪比的增加，所得估计趋于色散最小值中的最优值。
