【摘要】 船舶导航雷达是利用目标对电磁波的反射来发现并测定目标的距离和方位的船舶安全助航设备。本文进行了数字化船用雷达的功能分析,给出了使用计算机和 FPGA 及 DSP,带多种通信接口的总体设计方案,在性能上和功能上较传统模拟电路雷达都有很大进步和扩展,如可以计算并预测目标的航迹,进而对目标是否可能发生碰撞做出预警,还可以把雷达图像与电子海图叠加,显示所在海域的更多信息,雷达与 AIS 自动识别系统相连接,显示出被岛屿遮挡的雷达无法探测的目标等。还探讨了控制和显示单元的实现技术。更多还原

【Abstract】 The marine navigational radar is an auxiliary ship safety appliance which detects and determines the distance and bearing of the target,basing on the reflection of electromagnetic wave.The functions of this digitalized multifunctional marine radar are analyzed in this paper.The general plan is schemed out, with the use of computer,FPGA,DSP,and multi-communication interfaces.It greatly upgrades and enri- ches the capabilities as well as the functions of the traditional radar based on analog circuit.For example, it can calculate and forecast the track of the target,then make an early warning of the collision.It can also superpose the image of radar and electronic chart and display more information about the local sea area. The radar is connected to the AIS (Automatic Identification System),so the target once blocked by the islands can now be detected.Moreover,the realization of control and display unit is discussed.更多还原
