RESUMO

The new method of bispectral processing of the radar signals is proposed for determination atmosphere objects to recognize laminar and turbulent zones which are dangerous for aircraft flights. The new informative sign − the estimation of radar signals bicoherency - is suggested for studying volume distributed objects. The results of experimental studies perfomed by incoherent weather radar in centimeter wave band are described. The presented data demonstrate the advantages of the bicoherensy estimations as compared with traditional spectrum width estimation.
