提出了一种基于解重扩算法的GPS抗干扰实时接收机系统的硬件实现方案.此方案充分利用解重扩算法和GPS接收机的特点,将两者紧密耦合,并根据FPGA和DSP的不同性能,实现了资源的合理配置.实测数据验证表明,该系统不仅能够抑制干扰信号,而且可对卫星信号产生较大增益,实现多波束抗干扰.%Based on the despread respread algorithm, a realization scheme of GPS anti-jamming real-time receiver system is proposed.This scheme makes full use of the characters of the despread respread algorithm and GPS receiver, so the structure of the system is close coupled.In addition, the resources are allocated reasonably according to the different features of FPGA and DSP.Experimental results prove that the system is a multibeam anti-jamming receiver, which can not only suppress the jamming signals but also get extra gains of the satellite signals.
