摘　　要：为了解决雷达伺服系统的测试问题及满足部队模拟训练的需求,设计了基于VXI总线雷达天线转动信号数字模仿器。系统设计了A16/D16寄存器基接口电路,开发了软面板和仪器驱动程序。同时雷达天线转动信号产生功能电路实现中采用了特殊的模拟信号存储技术,使得电路具有成本低,性能高的特点。实际测试表明,所研制的VXI总线雷达天线转动信号数字模仿器能够产生幅度、频率可控的兼容不同体制雷达的转动同步信号,并可驱动多套负载,应用前景广阔。In order to test the radar servo system and satisfy the simulation training requirement of the army, the c-size digital emulator for signal of rotational radar antenna based on VXI bus is designed. The method to achieve circuit of A16/D16 register-based interface is put forward, the softpanel and drivers to apparatus are developed. In the process of realizing the circuit of signal of rotational radar antenna, special technique of analog signal storage is introduced, and thus the circuit performance is improved while reducing its expense. Practical test shows that the emulator can develop rotational synchro signals whose range and frequency can be controlled, and is compatible with radars of different system. It can also drive several sets of load.
