摘要
R/D和S/D转换电路在雷达系统中将天线的角度和转动速度变换成数字量,由数据处理机采集,计算天线的伺服控制参数,并作为测角、测距计算的输入参数。首先介绍了同步器/解析器的基本概念,然后给出了一种采用RD14531芯片实现的R/D和S/D转换电路,详细讨论了芯片的特性,电路实现和测试方法。
Angle and rotational speed of Antenna are becoming digital signals by the R/D and S/D converting circuit of radar system, and the data processing unit collect and calculate servocontrol parameters of antenna, the results are input parameters for angle and distance measuring. In this artile, it introduced the main characteristics of synchronizer and analyzer , the R/D and S/D converting circuit used cmos chip RD14531. Finaly, discussing the chip＇s function , cirtcut design and test method.
