| 摘 要： | 在射频仿真系统中,由于雷达系统的接收信号动态范围很大,而数字接收部分存在最佳输入电平范围的问题,所以中频接收需要实现信号的增益自动控制（即AGC功能）。该文提出了一种基于FPGA的数字AGC实现方法,给出了具体的硬件电路和详细实现算法。仿真分析和实验结果均表明,该数字AGC系统具有响应时间短、增益调节精度高、系统参数控制灵活的特点。

| Abstract: | In radio frequency simulation system（RFSS）,an automatic gain control（AGC） module is required in IF receive module,which can expand the range of the power of radar receive signals.A new implementation based on FPGA is proposed in this paper.The algorithm and the method of software and hardware design are described in detail.Simulation and experimental results show that this AGC module has the features of short response time,high regulation accuracy and flexible parameter control. |
