摘要
FPGA系统的应用使得舰船导航系统的数据处理能力和抗干扰能力获得极大提高,尤其在导航系统的图像收集和处理方面,基于FPGA系统的控制器能够实时处理大量通道的并发图像数据,因此其在舰船导航领域有着巨大的开发价值。本文设计舰船导航系统的硬件电路,并对内部的重要功能子模块进行介绍。在对图像收集的过程中,由于干扰的存在,因此设计了滤波环节,能够强化图像数据的准确度,最后采用正弦波和方波模拟双通道的输入信号,对该图像处理电路的功能进行仿真。
The application of FPGA system makes the data processing capability and anti-jamming capability of ship navigation system greatly improved. Especially in the image collection and processing of navigation system, the controller based on FPGA system can deal with concurrent image data of large number of channels in real time, So its navigation in the field of navigation has a huge development value. In this paper, the hardware circuit of the ship navigation system is designed, and the important function sub-module is introduced in detail. In the process of image collection, due to the existence of interference, so the design of the filter link, to enhance the accuracy of image data, and finally the use of sine wave and square wave analog dual-channel input signal, the image processing circuit function The simulation.
