摘要
An adaptive technique utilizing phase-only in interference suppression for a planar phased array is presented. No a priori knowledge of the interference directions is assumed, and the observed data are at the array output only: a single receiver system. The sequential orthogonal search directions in the phase space are predetermined, and the algorithm is very simple computationally. Using the criterion of minimizing the interference power and a soft constraint in the look direction, for a 1369 element planar array and three interference sources, the required phase distribution is reached after approximately 2200 time samples, or 11 ms (sampling rate 200 kHz). The convergence time varies approximately as a linear function of the number of interference sources, and it is essentially independent of the array size. Some computer results are given. © 1990 IEEE
