摘　　要：针对空时联合处理在GPS抗干扰方面应用时其性能取决于天线阵元数,从而带来计算量和体积增大的问题,提出了一种多级抗干扰GPS接收机的设计方法,在与空时联合处理同样的抗干扰性能的情况下具有较小的复杂度。最后给出的仿真结果表明其在减少运算量、提高抗干扰性能方面有优势。Since the anti-jam capability of joint space-time processing used in GPS depended on the number of antenna elements, a multistage anti-jam GPS receiver was proposed. It was of low complexity compared to the joint space-time processing receiver with the same anti-jam capability. Finally the simulation results presented prove it is of advantage in decreasing computation complexity and improve anti-jam capability.
