Jining Feng, Wang Jun, Diao Zhe-jun, Xiaobo Yang · 2013
Wideband Gaussian noise is a kind of important jammer to navigation receiver, usually is processed by increasing the thermal noise of frequency-locked loop (FLL), and there is few in-depth analysis on its effect to the performance of FLL. However, the effect of Wideband Gaussian noise jammer to FLL is associated with frequency discriminator, filtering and other sectors. Based on considering the key sectors, the effect of Wideband Gaussian noise jammer to the tracking error of FLL is studied deeply, and the closed-form solution is derived. The simulation results validate the conclusion.
