摘要
Abstract
small-scale GPS antenna array and its effect on the adaptive null-steering of received array pattern are in-vestigated.A square-arrangement GPS antenna array and a triangular-arrangement one are simulated re-spectively.The results show that the received patterns of element antennas are interfered by the mutual coupling between the element antennas, and the amplitude and phase imbalance of received signals by different element antennas in a triangular-arrangement antenna array is superior to that in a square-ar-rangement one.Thereafter, the influence of the amplitude and phase imbalance of a 7-elements GPS an-tenna array on the pattern nulling of array is researched further .The response curve of the null depth of received array pattern versus the illuminated direction of interference signal is presented .关键词
