在GPS抗干扰接收机研究中，首先要对天线信号进行模数变换，ADC的性能直接影响接收机抗干扰的动态范围和输出信噪比。
In researching GPS anti - jam receivers, since the signal received by the antennas should be transformed into digital signal first, ADC determined the capability and performance of the receiver.
因此您需要合适的测试设备与测试方法，来准确捕获雷达回波和杂散信号，进行雷达发射机及接收机指标测试，同时评估系统的抗干扰性及其他电路指标。
Suitable test system and method are need toaccurately capture and analyze the echo and clutter, even to test transmitterand receiver of Radar, and estimate the anti-jamming of Radar.
深入分析空时处理对导航信号的影响，指出空时处理可以可靠地应用于导航接收机抗干扰中，但要选取合适的最优准则和约束条件，使空时信号处理保持线性相位。
The important issue is analyzed. It is pointed out that STAP could apply to anti-jamming reliably in appropriate optimal criterions and constraints which make navigation signals remain linear phase.
