摘　　要：本文提出了一种对跳频信号进行解跳的方法。其基本思想是利用数字变频将跳频信号不同频率的各个跳段信号变频到统一载频上,使其转变为定频信号。文中着重论述了变频方案和内部参数的设计,并通过具体的例子说明了本方法基于HSP50214B的实现。This paper presents a method of dehopping the frequency hopping signals. The essence of this method is converting the various carrier frequency of the hopping periods to the same carrier frequency by digital frequency conversion,and then the frequency hopping signals are changed to fixed frequency signals.In this paper,the design of frequency conversion and the related parameters are emphasized. An example is provided to explain the implementation based on HSP50214B.
