METHOD OF FREQUENCY TRANSFORMATION FOR RADIO ENGINEERING AFTER AN INTERFERENCE SIGNALS ^{[№ 1 ' 2015]}
In article on transition points through a zero of the signal reflected from object and the radiated fluctuations the formation method is presented to sequence of rectangular impulses and their subsequent transformation as logic events with use of conjunction and a filtration of low frequencies. For the offered method of transformation the analysis is resulted and the estimation of a methodical error of transformation of a phase of the reflected signal in low-frequency area is received.

TECHNIQUE OF THE DIGITAL SPECTRAL ANALYSIS OF SIGNAL WITH IRREGULAR SAMPLES ON TIME ^{[№ 9 ' 2014]}
In article the technique of drawing up of a polynomial on samples of values of a signal with non-uniform digitization on a final interval of time is presented. For an approximating polynomial expression of spectral density is resulted and on its basis expression line a spectrum for the registered file loadout a signal with irregular digitization is formed. The made technique allows to make the digital spectral analysis of signals for discrete transformation Fourier with non-uniform sample on time of their values.

SPECTRAL TIME METHOD OF DETERMINING THE DOPPLER FREQUENCY THROUGH TARGETED TIME CHANGE ^{[№ 1 ' 2011]}
The paper presents a solution to improve the recognition resolution and measurement of the recorded Doppler signal on the basis of targeted spectral and temporal transformation of the noisy fluctuations of the Doppler swing. It provides the basic relationships for determining the sampling interval of the Doppler frequencies and recommendations on the iterations of the derivatives of Doppler frequency
