Abstract:
A mathematical model of a phase-lock loop system tracking breakdown probability definition in the conditions narrowband disturbance is given. Harmonic jamming with random initial phase is suggested as a mathematical model of narrowband disturbance. The results of performance evaluation of narrowband disturbance depending on its parameters as applied to the phase-lock loop system of the satellite navigation system users - terminals using BPSK signals are presented. It is shown that phase-lock loop system noise immunity in the conditions of narrowband disturbance decreases from 2 to 6 dB for different types of navigation signals in comparison with Gaussian noise.
