数字射频存储器(DRFM)正在逐步取代循环储频环路(FML)。使用 DRFM 克服了FML 的存储时间短、只能处理单个信号和有限的电子对抗能力的缺点。虽然 DRFM 有几种不同的结构形式.但是它们都完成基本相同的功能:把输入的射频信号的频率下变频,变成能够存储到数字存储器中足够低的频率上,然后再上变频变成原来的信号频率。DRFM 能在逐个脉冲基础上对多信号进行处理并利用软件控制产生干扰样式,因此使它成为任何系统中的一个有效的新增加的器件。
Digital Radio Frequency Memory (DRFM) is gradually replacing Cyclic Frequency Conversion Loops (FML). Using DRFM overcomes the shortcomings of FML’s storage time, handling only single signals and limited electronic countermeasures. Although DRFMs come in several different configurations, they all perform essentially the same function: down-converting the frequency of the incoming RF signal into a low enough frequency to be stored in digital memory and upconverting it to the original The signal frequency. DRFM can process multiple signals on a pulse-by-pulse basis and generate software-controlled interference patterns, making it an effective new addition to any system.
