Abstract

China has built, has been building, and will have built radio telescopes. Based on the most up-to-date pulsar noise measurements and design specifications of telescopes, we focus here on investigating the capability of pulsar timing observation using individual telescopes as well as their combination. We also calculate and discuss the feasibility to create the Chinese pulsar timing array project and the expectation for gravitational wave detection. As one will note, combination of large system, such as Five-hundred-metre Aperture Spherical radio Telescope (FAST) at Guizhou and Qitai 110 m fully steerable radio telescope at Xinjiang (QTT), will significantly increase the capability of current international pulsar timing array. We thus expect the breakthroughs in the FAST-QTT era.
