Simulations of a Low-Frequency Solar Radio Interferometry Array

This paper describes Low-Frequency Radio Interferometry Arrays, such as the LOFAR, LWA, and MWA projects. Based on reviewing various such arrays and advantages of the geography of Yunnan (particularly relevant to solar radio observations), we envisage to build a Low-Frequency Solar Radio Interferometry Array in the Yunnan Province, with the observation frequency range from 30MHz to 250MHz. We have simulated the UV coverage diagrams and the dirty beam maps under different station-weighting methods, for the array design of four existing stations array and an optimized array design. We discuss observation modes, radio interferences, low-frequency radio imaging, and other issues for this array. We finally analyze the possibility of observing solar CME, flares, and radio bursts with the proposed array.
