[0059] The present invention will be further explained below in conjunction with the drawings and embodiments
[0060] Reference figure 1 , The present invention is a method for determining the tolerance of the sparsely arranged array antenna for radiation and scattering. The specific steps are as follows:
[0061] Step 1. Determine the structural parameters, electromagnetic parameters and sparse arrangement matrix of the sparse array antenna.
[0062] 1.1. Determine the structural parameters of the sparsely arranged array antenna, that is, obtain the number of rows M, the number of columns N, and the array element spacing d in the full array. x And y cell spacing d y , The number of the radiation element in the array is (m, n), where m and n are the numbers of the radiation elements in the x and y directions respectively. The lower left corner of the array is the starting number, that is, the radiation at the lower left corner of the array The unit number is (0,0), and this is also...
