Abstract: Numerical simulations are conducted on the imaging of Fourier telescopy System with equalspaced antenna array in T shape geometries, and the imaging quality is evaluated by the Strehl distribution of different targets. The results testify that the array with the same numbered antennas in each of the three arms gains the target’s spectrum distribution that is the most symmetrical in the horizontal and vertical directions, and can obtain good imaging quality and high Strehl ratio, for antenna arrays of such structure, the images are reconstructed for multiple objects with 3 to 18 antennas in each arm. It is found that, while the single arm’s antenna number is no more than 10, increasing the number of antennas can obviously improve the reconstructed image’s quality and distinguish the ob
