METHOD OF PROCESSING BROADBAND SIGNALS AND DEVICE OF PHASING ANTENNAE RECEIVING BROADBAND SIGNALS, MAINLY FOR NO-EQUIDISTANT ANTENNA ARRAY Russian patent published in 2016 - IPC H01Q21/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention can be used for receiving broadband signals, for example, in the system for collecting telemetric information from on-board equipment of space vehicles. Invention discloses a method of processing broadband signals and a device of phasing antennae receiving broadband signals, mainly for no-equidistant antenna array. Pulse sequences of starting the ADC for sampling signals of different antennae of the array after the band filter of intermediate frequency amplifier are shifted each within its own delay unit to its own sampling period share, which is equal to the residue from the division of difference of signals path times from the phase centres of the slave and the reference (master) antennae to corresponding inputs of their analogue-to-digital conversion devices. Feeders length is selected in such a way that the path time from the reference antenna to the input of its ADC is less than the path time from any other antenna of the array to its ADC input by the difference of signals path in free space between the most remote antennae in the array. With a delay sufficient for arrival of a signal from the antenna with the highest positive difference of signals path times from the phase centres of the slave and the reference antennae to corresponding inputs of their analog-to-digital conversion devices, to each sampling cycle of each memory array sampling reports with indices related to one signal wave front are selected one from each antenna from the respective arrays and are summarised in the directional pattern shaping unit.

EFFECT: faster operation of the antenna field antennae phasing device when receiving from the antenna field some broadband signals, carrying, for example, telemetric information on the state of spacecraft onboard systems.
