摘要

研究了频率变化缓慢的微弱窄带信号的频率跟踪问题。提出了一种扩展的卡尔曼滤波器，该滤波器利用信号性质的先验知识来克服问题固有的非线性和极低的信噪比所带来的困难。

An Extended Kalman Filter Frequency Tracker for High-Noise Environments

The problem of constructing a frequency tracker for weak, narrowband signals with slowly varying frequency is considered. An extended Kalman filter is proposed that uses prior knowledge of the nature of the signal to overcome the difficulties presented by the inherent nonlinearity of the problem and the very low signal-to-noise ratios.
