用FIFO实现DRFM距离欺骗的应用与研究

A FIFO-based distance deception realization of DRFM

提出了一种基于FIFO实现数字射频存储及距离欺骗的设计思路。系统对接收到的雷达信号进行实时、高速采集,并利用FIFO特性对采集的数据流延迟一恒定时间,通过控制FIFO读写使能信号之间的延时实现DRFM的距离欺骗。应用FIFO大大简化了DRFM系统的设计,且提高了系统稳定性和可靠性。

This paper suggests a design solution of realizing the distance deception of DRFM based on FIFO. The system real-timely collects with high-speed the radar signals firstly, and controls the delay between the read and write enable signals of FIFO to realize the distance deception of DRFM through the FIFO's character of delaying an invariable time for the sampled data flow. The application of FIFO simplifies the design of DRFM and raises the stability and reliability of the system.
