Fourier Telescopy （FT）is an active imaging technique that has a unique advantage for high resolution of deep space object which is very small and dim.The traditional three square beam imaging′s scan time is too long and it is suitable only for stationary targets.To carry out high resolution imaging for moving targets within a few seconds,there have been several different types of multi-beam emission array configuration.T-type configuration is one with the least redundant structures.This paper uses T-type and 6 beam launching configuration to introduce the principle of Fourier imaging telescope.The relationship between T-emission array plane and the spatial frequency plane is derived.By analyzing the impact of spatial frequency on image quality,the advantages of T-type Fourier imaging telescope array are verified.Through computer simulation,the reconstructed images under different conditions are obtained.Image quality can meet the requirements and imaging time is shorter at the same SNR.It provides a guide line for the indoor and outdoor experiments and also provides a reference for more beam and other emission array configuration.
