Abstract
This paper proposes a structure of a broadband instantaneous frequency measurement receiver consisting of an analog correlator and a digital frequency estimation calculation unit. A feature of this structure is the use of only two ADCs regardless of the width of the operating frequency range. Expansion of the frequency range is achieved through the use of channels with comparators, and each channel with a comparator doubles the width of the operating frequency range. The procedure for calculating the main characteristics of a IFM receiver is given: delay time and the number of channels with comparators. Simulation results are presented showing a comparison of the standard deviation of the frequency estimation for the known broadband structure presented in the literature and the proposed structure.
