Sidorenko R. The method of rising interference stability radiometric system by the principles of suppressing interference that focused on the spectrum in the radiometer by the rising of sensibility by the accumulation and noise decorrelation.

The object is a process of providing interference stability of the radiometric system. The purpose is increasing of interference stability radiometric systems on the principle of accumulation, noise decorrelation and compensation of narrow-band interferences in the receiving tract. Methods were conducted within the theory of correlation-spectral analysis of casual processes (statistical theory of the radio engineering systems). Innovation - there was firstly received the collecting of analytical expressions for determinate of ratio signal/noise on the exit of separate functional elements of radiometer where were counted the influence of narrow-band interference. The method of increasing of interference stability of radiometers with waves of millimeter range which based on the compensation of narrow-band interference in the entrance chain of receiving tract received further development. Analytic expression for definite of degree strangle interference by the entrance chain of receiver was firstly obtained in this working. This expression allows estimate winning in suppression of interference for any ratio of entrance signal bands, interference bands and their central frequencies. The method of increasing of sensibility of radiometers with waves of millimeter range got further development. This method is different from known by using of n-challenging delay line with summering of signal and removal influences of the intensification channels on exit signal. Job performances are realized in the scientific metrological center of military standards (the act about realization of results scientific researches). The sphere of application is the aerospace branch organizations.
