METHOD FOR JOINT PROCESSING OF TELEMETRY SIGNALS WITH TIME DIVISION OF CHANNELS REGISTERED ON SPACED-OUT MEASURING TOOLS Russian patent published in 2023 - IPC G08C19/28 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, telemetering equipment, and can be used in reception, recording, and joint processing of telemetry signals with time division of channels transmitted from an aerial vehicle and recorded on spaced-out measuring tools by securing the instantaneous values of the signals at an intermediate frequency to resolving apparatus. Substance: joint processing of telemetry signals is conducted at an intermediate frequency to resolving apparatus by implementing the principles of coherent addition. For this purpose, operations of compensation for the phase difference between signals registered in different spacing channels are performed, and said signals are multiplied by the weighing coefficients characterising the dependence of the signal amplitude change on the transmission coefficient change in each spacing channel. Multiple variants of the implementation of the sum signal at different set values of the phase differences in signals registered in different spacing channels are therein formed. For each variant of the implementation of the sum signal, the value of power of the received sum signal is determined. The values of power of all variants of implementation of the sum signal are compared. The sum signal with the maximum value of power is selected.

EFFECT: reduction of losses in the results of telemetering occurring in conditions of low values (less than one) of the signal-to-noise ratios.
