Abstract
A simulated Doppler navigation beacon system providing second order spatial diversity with respect to excitation of its commutated 2-dimensional main (coordinate) array and a linear reference array. For elevation measurement, the main array excitation is advanced in elevation, one element at a time during each scan cycle, but the lateral (horizontal) excitation is varied pseudo-randomly in both main and reference arrays while maintaining the same lateral spatial relationship between the main and reference array element pair excited at any time. The reference array comprises a larger number of elements than the horizontal elements in said array and the adjacent group of reference elements excited during any scan cycle of the main array is shifted laterally for each succeeding main array scan cycle.
