Abstract

The problem of time-frequency analysis for barely visible radar stations signals, based on windowed Fourier transform was considered. Improved algorithm, based on integration of Fourier transform data was suggested. Algorithm application gives us the possibility to take into account characteristics of such signals, especially with low signal/noise ratio.

Keywords: time-frequency analysis,integration, barely visible radar stations.
