Abstract :
A novel time-domain method of estimation of instantaneous frequency of signals under the influence of noise is presented. The methodology is exemplified by its application to the estimation of Doppler frequency shift which is encountered both in aerospace and biomedical engineering. The estimation method is a nonlinear adaptive algorithm which exhibits a high degree of immunity to both external noise and misadjustment of internal parameters while offering structural simplicity crucial for real-time applications.
