MULTICHANNEL ULTRA-WIDEBAND RADIO RECEIVER Russian patent published in 2023 - IPC H04B1/16 H04B1/00 

FIELD: radio engineering.

SUBSTANCE: used in wideband ultra-high frequency (UHF) radio receiving devices, in particular in ultra-wideband aviation electronic monitoring systems that have restrictions on weight and size characteristics and power consumption. In a multi-channel ultra-wideband radio receiving device, the antenna is made in the form of a receiving antenna system, in each receiving channel the preselector consists of an active k-channel frequency-selective splitter and k bandpass filters, the operating frequency converter to an intermediate frequency in each channel is made in the form of k quadrature demodulators, the generator is made in the form of a local oscillator module that forms a grid of k frequencies. In the phase shifter module, each j-th frequency component of the heterodyne frequency grid is divided in-phase using a common-mode power divider into n components, for which an individual phase shift is added. The antenna system is a multibase non-equidistant n-channel phase interferometer.

EFFECT: increasing throughput and reducing response time to new threats, avoiding missing threats and simultaneously suppressing targets across the entire operating frequency range, and minimizing hardware costs by expanding the instantaneous swath.
