Abstract.   A method is proposed for improvement of accuracy of average frequency measurement in acousto-optical spectroanalyzer with spatial non-invariant response based on calibration of the frequency response and frequency scale. The method is reported to ensure reduction of instrumental error of frequency measurement from 4,5 to 0,1 MGz.
Keywords: acousto-optical spectroanalyser, frequency measurement, radio monitoring.
