Abstract :
Summary form only given. A new method for decollimating the quantization lobes (QL) of a scanned array of sub-arrays applies pseudorandomization to the sub-array phases. This breaks the QL up into several lobes, of roughly equal, and lower, amplitude, providing the number of elements is large and the random numbers are good. Most random number tables (and generators) of 100 numbers are only partially random; the random number table should spread out the QL energy, with no excessive peaks. New test cases utilize a linear array of 100 or 102 isotropic radiators, with sub-arrays of 2 or 3 elements, and half-wave element spacing. A random number table (from 0 to 1) is used to adjust the phase applied to each sub-array
