FIELD: radio engineering, communication.
SUBSTANCE: panoramic radio receiver comprises a controlled attenuator, a high-frequency link, an analogue-to-digital converter (ADC), a digital signal processing unit, which comprises a set of m digital modulator-filters, the control input of the controlled attenuator is connected to the output of a stimulus former, which is connected to the control bus of the digital signal processing unit, a personal computer connected to the digital signal processing unit, a tunable rejection filter unit connected to the controlled attenuator, high-frequency link and stimulus former, and the stimulus former is connected to the ADC, wherein m=Δf/ΔF, where Δf is the transmission bandwidth of the high-frequency link, ΔF is the transmission bandwidth of each digital modulator-filter, the digital signal processing unit also includes a decision device, a computing device and a storage device.
EFFECT: high noise-immunity and efficiency of the panoramic radio receiver when receiving and monitoring radio signals with different types of modulation.
