Recurrent Bayesian estimator system for Doppler frequencies
Abstract
Some aspects of designing a quasi-optimal recurrent Bayesian estimator of Doppler frequencies employing tracking demodulators of FM signals are examined. An algorithm of system operation is proposed, and the precision of frequency measurement is assessed. A symbolic circuit is proposed for a quasi-optimal Doppler frequency meter employing a tracking demodulator in combination with a double-point extrapolator.
