The analog-digital device of two-channel monopulse bearing measurement of radio radiation sources at the carrier frequency of input signals consists of sum and difference channels, a phasor system for forming quadrature components of input signals at the carrier frequency of input signals, a heterodyne and a phase rotator. For bearing measurement, the radiation source additionally contains four analog-to-digital converters of the main and additional channels, a serial interface and a digital signal processor.
