WebAn astronomical interferometer or telescope array is a set of separate telescopes, ... (the thinned-array curse). The combined effects of limited aperture area and atmospheric turbulence generally limits interferometers to observations of comparatively bright stars and active galactic nuclei. WebIf the array has been thinned so that only 25 percent of elements are used, its main beam gets a −3 dB- beamwidth of less than 1 degree. However, about 75 percent of the power is …
WebDec 24, 2015 · A novel thinned array with symmetric distribution along the array center is proposed in this paper. The proposed symmetric thinned array is based on the theory of unequally spaced array and the amplitude of each element in the array can be changed by introducing the weighted function.
