DRFM of Digital Channelization Based on Fractional Fourier Filtering
现代战场环境电磁日趋密集和复杂,各类信号相互混迭,同时各种相参雷达采用脉冲压缩技术以及相参处理方法,抗噪声和抗干扰能力大大增强,特别是采用线性调频(LFM)信号满足了雷达大威力、低截获的功能设计需求,抗干扰能力也得到提高.常规的数字储频(DRFM)采用宽带采集,在数字上对宽带信号进行调频、叠加等调制处理,在瞬时带宽内调制样式、参数是相同的,此处理方式导致瞬时带宽内多信号时,无法针对性施加不同的调制样式,以致干扰粗放、不够精确.为实现精确、有效的干…查看全部>>
In the modern battlefield environment,electromagnetic is becoming more and more intensive and complex,and all kinds of signals are mixed with each other.At the same time,various coherent radars adopt pulse compression technology and coherent processing method,and their anti-noise and anti-jamming abilities are greatly enhanced.In particular,the use of linear frequency modulation(LFM)signal meets the radar's high power,low interception function design require…查看全部>>
