【摘要】 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.更多还原

【Abstract】 A radar moving target generator based on personal computer is introduced. Moving targets generated by software can be manipulated and edited. Target data are transformed into radar signals, including the trigger pulses, the azimuth pulses, the north mark and the radar video signals through the interface circuits. The repetition cycle of the trigger and the number of the azimuth pulses can be selected by software. The width and the polarization of the trigger pulses, north marks and the video pulses are selectable. This target generator can be used as the signal source for VTS simulator and ARPA simulator.更多还原
