Abstract

The paper considers the techniques of processing of signals from an ionosphere LFM-probe, permitting to detect additionally the interference concentrated in spectrum, and to measure their characteristics. The approximate identification of the resulting distribution shape was performed based on estimates of counter-excess and of the entropy coefficient. The value of differences between the samples was assessed based on the criterion of detection of large errors in exponential measurements. During the experimental approbation of the techniques, the probability of right detection of the lumped interference made up 95%.
