FIELD: radio engineering, communication.SUBSTANCE: apparatus comprises series-connected measuring unit, signal selector, period computer, storage unit, parametric sequence identifier and a threshold device. The apparatus also includes series-connected period averaging unit, signal arrival time extrapolator, time comparing device and additional threshold device. Inputs of the period averaging unit are connected to the output of the threshold device and the second input of the storage unit, the third output of which is connected to the second input of the time comparing device.EFFECT: high probability of correct identification of signal sequences from the same type of sources.3 dwg |
