Recognition of signals on a noise background in an acoustooptic spectrum analyzer
Abstract
The spectral recognition of signals in an acoustooptic spectrum analyzer (ASA) on a background of the external and internal noise of the optoelectronic system (OS) of the ASA is examined. An analysis is made of the influence of the number of quantization levels of the solving device of the OS and the signal-noise ratios on the probability of correct recognition and erroneous solutions.
