METHOD TO DETECT RADIO SIGNALS Russian patent published in 2011 - IPC G06K9/00 

FIELD: information technologies.

SUBSTANCE: previously matrices are generated from counts of spectral representations of reference detected classes of radio signals, their own values are calculated, the noiseless ones are selected, and criteria vectors are generated out of them. When detected, a received radio signal is digitised in time and is quantised by level. Then its spectral representation is calculated, from coefficients of which a matrix is generated, its own values are calculated, and a vector of criteria is generated in a manner similar to reference samples. Received criteria are compared to criteria of reference samples, and a decision is made to relate the received radio signal to one of the reference samples of the detected classes.

EFFECT: higher probability of proper detection of radio signals under action of noise and interference, due to selection of a criteria vector resistant to noise of components.
