| 摘 要： | 多元阵天线阵列常被用于侦查和定位系统,相位差变化率则是单站无源定位中常用的观测参数。文中介绍了一种基于AD公司多片2.5 GSample·s-1 的高速AD9739型号D/A转换器,采用DDS技术的多通道信号模拟器。经测试,该模拟器能较真实地模拟出,多元阵天线阵列所接收到的宽带线性调频信号波形的相位差变化信息。

| Abstract: | Multiple antenna array is often applied in the detection and location system, in which the phase change rate is commonly used in single observer passive location of the observation parameters. This paper presents a multi-chip-based high-speed AD company 2.5 GSample·s^-1 D/A converter AD9739 with DDS multi-channel signal simulator. Tests show that the simulator can achieve realistic simulation of phase change of the wideband linear frequency modulated signal waveform received by the multi-element antenna array. |
