| 摘 要： | 介绍了水下多传感器阵列的数学模型，通过构建一套软硬件系统，实现了水下多传感器阵列信号的建模与硬件仿真。通过改变阵型、阵元间距、阵元个数、信号形式、信号频率、入射角度等参数实现了各种不同条件下仿真信号的模拟输出。最后采用NI的9215A数据采集模块对多通道输出信号进行采集．并通过相关函数方法验证了各个通道间信号时延的准确性。

| Abstract: | A brief introduction of the mathematical model of the underwater multi-sensor arrays signal is shown. A set of hardware and software is constructed to achieve the functions of multi-sensor array signal modeling and hardware emulation. Analog ouput signals on different conditions are realized depending on changing array styles, numbers of array-element, signal waveforms, signal frequency and direction of arrivals. Analog output signals are acquired using NI USB-9215A data aqusition hardware and the time dela... |
