Abstract
Using the phase of a signal as an informative parameter usually allows for the
highest efficiency of signal isolation from interference and the accuracy of estimating its parameters.
However, in some cases, in particular in conditions of intense interference and fluctuations in signal
parameters caused by the movement of a moving object, a decrease in the information content of the
phase caused by its "jumps" into neighboring phase cycles may cause a deterioration in the quality
of functioning of the equipment of radio engineering systems, which makes it advisable to exclude
the phase from the vector of measured parameters.
The study of this issue was carried out in the work by comparing the characteristics of
synchronization systems for communication and navigation equipment with phase and frequency
auto-tuning of the frequency of the reference oscillator. At the same time, it was assumed that the
equipment was located on a mobile object and operated in conditions of intense interference.
The unique characteristics of Low Probability of Intercept (LPI) waveforms, which are based on wideband specialized modulation techniques, LPI signals not only provide high resistance against electronic jamming but also significantly reduce the detectability of these signals, thereby establishing LPI signals as an effe...

Electromagnetic sensors of the inductive type are widely used in industrial systems, scientific research, and measuring equipment. However, during their operation, parasitic angular modulation may occur, leading to distortion of measurement results and a decrease in the accuracy of useful signal extraction. Therefore,...

Estimating the argument of an electrical impedance is an important task in many engineering fields. Modern systems usually employ data acquisition systems to sample and digitize the voltage and current signals obtained by stimulating the unknown impedance with a sinusoidal signal. The presence of nonideal phenomena in...

Accuracy and intolerance to interference of GNSS receivers depend on the efficiency of tracking modules. To achieve better characteristics, designers should implement various issues, affecting the process of tracking in these modules: integration interval, spacing and configuration parameters of PLL and DLL. The articl...
