10 436 Í 55 Design and Testing of a Ground-based System for Phase Stabilized Standard Frequency Transmission WANG Jin-qing 1,2 JIANG Yong-chen 1,2 GOU Wei 1,2 YU Lin-feng 1,2 LIU Qing-hui 1,2 FAN Qing-yuan 1,2 LOU Fang-xun 1,3 LAO Bao-qiang 3 (1 Shanghai Astronomical Observatory, Chinese Academy of Sciences, Shanghai ) (2 Key Laboratory of Radio Astronomy, Chinese Academy of Sciences, Nanjing ) (3 Guilin University of Electronic Technology, Guilin ) ABSTRACT In this paper, a 1.5 GHz phase stabilized frequency transmission system is described. Compatible with the coaxial cable and optical fiber transmission media, the system has both the capabilities of real-time and post phase compensation. The phase stabilizing principle of the equipment is analyzed, and its performance is evaluated. Under the test environment, the results of the prototype system based on a coaxial cable show that the real-time compensation mode can improve the phase stabilities by more than 112 times in comparison with the uncompensated cables. The frequency stabilities are also improved significantly with a 7-second integration time, and one order-of-magnitude improvement is achieved after 60 seconds. The post compensation mode can improve phase fluctuations by 40 times. The frequency stabilities can be improved significantly after 2.5-second integration, while a 10-fold enhancement is achieved after 40 seconds. With longer integration time, both real-time and post compensation modes can improve the frequency stabilities by more than 1.5 orders of magnitude. The proposed equipment can effectively reduce slowly stretching effects due to the factors such as the temperature coefficient variations of the transmission medium and mechanical disturbances. Key words instrumentation: interferometers, methods: data analysis, statistical, time
