水下多目标信号源的研制

Underwater Multi-source Signal Generator

针对水下多目标定位及跟踪技术的要求,设计并研制了一种用于水池试验、能够同时模拟输出多个水下目标反射回波或目标多亮点回波的多目标信号源;解决了信号源多通道独立、联合信号输出问题,实现了长数据的不间断输出和各通道输出波形、通道参数的实时可控;试验表明该信号源可同步模拟4个动态目标的方位、速度、距离等回波信息或目标亮点,实时性好,使用方便,且具有一定的通用性。

The purpose of this paper is to propose an underwater universal multi source signal generator （MMSG）, which can well simulate underwater multi source echo signals and offer the water tank experiment a signal generating platform. The problem of how to produce multi-channel signals independently or jointly is solved, and the capabilities of generating long data uninterruptedly, and controlling the parameters of the outputs and channels synchronously are achieved. The experiments show that four moving targets＇ echo information, such as the DOAs, speeds, distances, or bright spots of targets, can be simulated by using this MMSG. And 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 multi-channel arbitrary signal generator.
