Abstract
A microwave receiver measures the frequency F of a microwave signal in a band of frequencies whose maximum frequency is Fmax. The receiver has N frequency measuring digital stages EE, . . . Ek, . . . EN providing N ambiguous frequency measurements FmFm, . . . Fmk, . . . FmN of the signal received, the signal received being sampled, in each digital stage, at a respective sampling frequency FeFe, . . . Fek, . . . FeN. The receiver further includes an ambiguity resolving device () receiving the N frequency measurements and providing the frequency F of the signal received. Each frequency measuring digital stage Ek has a one-bit analog/digital converter () fed directly with the microwave signal received by the receiver, means for performing a discrete Fourier transform on the basis of the samples output by the one-bit converter, and at least one detector () of spectral line maximum of the discrete Fourier transform providing a frequency measurement Fmk of the signal received.
