| 摘 要： | 基于某雷达对抗设备的测试环境对雷达模拟信号源在高速扫频情况下输出功率精度的要求,提出了一种联合运用开环和闭环控制方式实现信号源在宽带高速扫频情况下进行高精度功率控制的设计方法,详细阐述了其实现原理,并将其应用于某X波段雷达模拟信号源的设计过程中,实现了在扫频的频点驻留时间不小于100ns条件下,输出射频功率误差不大于0.5dB的技术指标.

| Abstract: | Based on requirement of high-precision RF output power of the radar simulated signal source running in high-speed frequency-sweep mode in the application of a radar EW equipment test,A design method on a combination of open-loop and closed-loop control for high precision power control is proposed, elaborating its principle and implementation. And in the application of a X band radar signal design, under the frequency sweep dwell time of not less than 100nsconditions, RF output power error is not greater than 0.5dB. |
