水下多目标模拟信号源的设计及实现

为满足水下多目标跟踪与定位水池实验系统对多通道多参数模拟信号源的要求,设计并研制了一种基于USB(通用串行总线)和FPGA(现场可编程门阵列)的水下多通道多参数模拟信号源,解决了信号源各通道相互独立或联合输出、长数据不间断输出和各通道输出波形、通道参数实时可控问题.实验表明该信号源实时性好、使用方便,具有一定的通用性.

Design and Implementation of Underwater Multi-target Simulated Signal Generator

In order to satisfy the requirement for the multi-channel multi-parameter simulated signal generator in the underwater multi-target localization and tracking, an underwater multi-channel multi-parameter simulated signal generator based on USB and FPGA is designed and developed. The key problems of producing multi-channel signals independently or jointly, generating long data uninterruptedly, and controlling the parameters of the outputs and channels synchronously are solved. The experimental results show that this signal generator is real-time and convenient, and can be used not only in the study on multi-target detection and tracking, but also as a multichannel arbitrary signal generator.
