摘要
通过对VCO工作性能及控制电路的分析,对距离在一百米左右的两个或多个VCO系统设计了有线传输的跳频同步方案。利用CPLD对VCO数字控制信号的并行采集、串行传输、串行接收和并行输出来控制多个VCO输出工作频率的同步。实践证明该方案简单可行、成本低、同步时间快和抗干扰性能强,已成功应用在雷达信号检测模拟器及雷达诱饵的设计中。
Through analyzing VCO performance characteristic and control circuit,a project of frequency-hopping synchronization by wired transmission is designed for two or more VCO which distances are around 100 meters.The synchronism of those VCO export working frequencies was controlled by VCO digital control signals which were parallel collected,serial transmitted,serial received and parallel output by CPLD.Practice shows that this design is simple and feasible,low-cost,synchronization time is rapid and anti-jamming is strong,this design has been used in the design of radar signal detection simulator and radar bait successfully.
