Based on data rate conversion technology, wideband digital EW receiver is able to achieve high intercept probability, high sensibility and the ability of approximately real-time signal processing.
The basic function of digital down-conversion technology is to transfer wideband high speed data signals into narrowband low speed data signals, so that DSP can process them in real time.
数字下变频技术的基本功能是将宽带高速数据流信号转变成窄带低速数据流信号,以便DS P实时处理。

However, extending the upper frequency of such function signal generator is limited by the read-out time of the memory and the conversion rate of the digital-to-analog converter.
