摘　　要：介绍了一种利用高精度自整角机的轴角/数字转换器实现雷达方位角测量的方法,给出了实现雷达角位置测量的硬件电路和软件设计。着重研究了自整角机随雷达旋转时产生三相模拟信号通过隔离转换电路转换成正、余弦信号,输入到单片机MSP430F149的轴角/数字转换电路中转换成二进制数字信号,供雷达终端显示或转发。该系统已在实际中得到成功应用,测试结果表明,采用的方案不仅设计简单、满足测量精度要求,而且能保证系统的可靠性。The angular position detection of radar azimuth based on high accuracy autosyn/digital converter is introduced. The design of hardware circuit and software is presented for measuring the radar azimuth. The sine,cosine digital signal is converted by three line autosyn signal and its output is a binary code based on singlechip of MSP430F149. The system code can show or transmit by radar terminator. The testing result shows that the applied scheme can satisfy the measurement accuracy, the circuit is simple in form, and the reliability of designed system is proved in application.
