On the relation between the solar flare activity and characteristics of radioemission from active regions

The results of observations of active solar regions, carried out with RT-22 and TIA-1500 radiotelescopes, are given. RT-22 observations were carried out at wave lengths 0.82, 1.35, 3.2 cm in 1972-1982 yrs.; TIA-1500 - at wave lengths 3.6 and 7.7 cm in 1981-1982 yrs. Radiowave fluctuations are analyzed by the methods of correlation and spectral aalysis. High correlation between intensity fluctuations and radiowave polarization at wave length lambda=3.6 cm, as well as at wave length lambda=7.7 cm is found. Mean fluctuation power of radiowave flux grows with increasing a wave length
