DEVELOPMENT OF A SOFTWARE ALGORITHM FOR AUTOMATIC DETECTION OF NONLINEAR DISTORTIONS OF A USEFUL SIGNAL IN THE RECEIVING CHANNEL OF A FIRE CONTROL RADAR WITH A LARGE DYNAMIC RANGE

The paper presents the results of developing a software algorithm for automatic detection of nonlinear distortion of video signals at the output of the receiving path of a fire control radar due to temporary overloads of the receiver when changing the range to the target in a wide range, as well as when changing the effective scattering area (ESA) of the radio wave.The detector of nonlinear distortion of video signals operates on the principle of recognizing and measuring the amplitudes of individual spectral components in the spectrum of a video pulse packet at the receiver output. The distinguished advantages of this type of detector are reliability, accuracy and simplicity in practical implementation
