Tianlai Dish Array Multi-Beam Forming

Deng, Furen

Tianlai Array is a radio telescope for HI mapping at Hongliuxia, the Xinjiang Uygur Autonomous Region. The group is leaded by Xuelei Chen. Tianlai array works at 700 to 800 MHz and consists of two parts, Dish Array and Cylinder Array. Recently we have succeeded in digital beam forming using 16 dish antennae for Tianlai Dish Array, as part of our effort for FRB detection. At Present we can form 16 beam for each polarization. We have achieved about 100 times improvement in magnitude and 10 times improvement in sensitivity comparing with single antenna.
