MULTICHANNEL RADIO MONITORING DEVICE Russian patent published in 2019 - IPC H01Q21/00 

FIELD: radio engineering; electronics.

SUBSTANCE: invention relates to radio electronics and can be used in automated receiving centers of radio monitoring and radio communication of stationary and mobile types. Radio monitoring device comprises an antenna array consisting of N receiving antennae, N primary processing and signal filtering units, each of which is connected to a corresponding receiving antenna and includes series-connected primary signal processing unit and a controlled filter unit, comprising K filters, as well as first and second switches, a detection and tracking unit, K data processing and storage units and G units for final processing and display of information, inputs of each of which is connected to corresponding outputs of the second switch. Each of the primary signal processing units comprises an analogue receiving unit, an analogue-to-digital converter and a step-down frequency converter connected in series, as well as a control unit, a receiving channel synchronization unit and a test signal unit. Detection and tracking unit includes signal spatial processing unit, a Fourier transform unit, a unit for detecting and unit measurements and a block of trajectory tracking of objects connected in series, as well as a unit for calculating beam pattern coefficients and a control unit for viewing. Each data processing and storage unit includes a signal spatial processing unit, a controlled-delay data storage unit and a data sampling unit connected in series, as well as a beam pattern calculation unit.

EFFECT: technical result consists in improvement of reliability of device and increase in maximum delay time of delayed access.
