N2 - IF digitization of the DVOR receiving system requires a high precision clock. In the DVOR receiving system, there will be a clock jitter with Gaussian white noise at a high carrier frequency, and the jitter will reduce the demodulation performance. In this paper, we propose a scheme for demodulating azimuth in DVOR receiving systems, and then the influence on the accuracy of bearing information is studied by using the clock jitter model commonly used in the literature. Additionally, DVOR signal clock compensation is proposed, to reduce sampling and signal processing effects caused by clock jitter. This compensation method could significantly improve the accuracy of bearing information in the receiving system.
