  • Published Date: April 14, 2010
  • This paper compiles performance measures of antenna arrays of radioheliographs constructed by Japan,Russia,France,China,and U.S. America specially for observing the sun,and synthesis arrays of U.S. America,India,and Brazil for observing stars and the sun.Several typical antenna arrays and receivers are illustrated.The formulas of sensitivity and dynamic range for antenna arrays with equal or unequal antenna apertures are listed,together with those for sizes of fields of views and spatial resolutions.Readers can use the formulas to calculate,analyze,and compare the specifications of the antenna arrays.
