Abstract

Detecting and analyzing the spectral content of intercepted microwave and millimeter-wave signals over a very wide bandwidth in real-time and with high resolution is an essential capability in many applications, ranging from commercial and surveillance, to defense. This is typically implemented by dividing the RF spectrum to be analyzed into narrower frequency slices, known as channelizing, which effectively sub-rates the input bandwidth and allows for signal processing in parallel with increased resolution [1].

基于宽带参数光梳的信号处理
在非常宽的带宽上实时、高分辨率地检测和分析截获的微波和毫米波信号的频谱内容,是从商业、监视到国防等许多应用中必不可少的能力。这通常是通过将待分析的RF频谱划分为更窄的频率片来实现的,称为信道化,它有效地对输入带宽进行子速率,并允许在增加分辨率的情况下并行处理信号[1]。
