介绍基于PC机的雷达信号源的设计,该信号源利用程序产生雷达运动目标,并可对运动目标进行操纵和编辑.通过接口电路将运动目标的数据转换为雷达信号,包括触发脉冲、方位脉冲、正北标志及视频脉冲信号.触发脉冲周期和方位脉冲个数可通过程序设定,触发脉冲、正北标志脉冲及视频脉冲宽度可以调整,极性可以选择.利用FIFO(先进先出移位寄存器)做为接口板的目标数据存储器,使得接口电路大大简化.该信号源可以为船舶交通管理系统模拟器和ARPA模拟器提供运动目标.
This paper introduces the design of the radar signal source based on PC, which uses the program to generate the radar moving object and can manipulate and edit the moving object.It converts the data of the moving object into the radar signal through the interface circuit, including the trigger pulse, azimuth pulse , The north sign and video pulse signal. The number of trigger pulse period and azimuth pulse can be set by program, the trigger pulse, the north mark pulse and video pulse width can be adjusted, the polarity can be selected. Register) serves as the target data memory for the interface board, simplifying the interface circuitry, which provides the movement targets for the ship’s traffic management system simulator and ARPA simulator.
