摘　　要：针对新的使用DS/FH混合扩频信号的测控体制,为了分析DS/FH混合扩频信号受干扰时的测量性能,建立了DS/FH混合扩频信号的发送与接收模型。通过分析3种不同干扰信号的特点,分别为宽带阻塞式干扰,部分频带干扰和高斯白噪声,得出在干扰条件下的接收信号信噪比变化。最后通过理论仿真得出在干扰条件下DS/FH混合扩频信号的测速测距性能。The measurement performance with the interference is presented with the new DS/FH hybrid spread spectrum signal system. The DS/FH system model is established. The change of the SNR ratio is obtained by analyzing the characteristics of three kinds of interference signal such as partial-band noise jamming （PBNJ） , wide-band noise jamming （WBNJ） and additive white Gaussian noise （ AWGN）. Then the ranging and velocity measurement performance is got through the simulation.
