Extraction of the in - pulse characteristics of signal based on direct sampling from if signal and quadrature coherent detection 基于中频直接采样正交相干检波技术的信号脉内特征提取
In order to improve signal noise ratio ( snr ) , wavelet denoising is used , and the radar in - pulse characteristics is extracted by wavelet - ridge , radar emitter signal sorting is realized by neural networks 该方法首先对接收到的雷达信号进行小波去噪,达到提高信噪比的目的,然后利用小波脊线法准确提取其脉内特征参数,最后基于神经网络实现信号的分选。
Realizing the impact of chirp on the effect of carrier phase , some analytical expressions of chirped few - cycle pulses are also calculated , such as frequency gravity , pulse energy , center of gravity of time , effective pulse width , etc . results show that chirp makes the pulse characteristics more sensible to carrier phase , and chirp has greatly increased the pulse width when the carrier phase takes effect 考虑到啁啾对载波相位作用程度的影响,导出了啁啾脉冲的频率重心、脉冲携带的能量、脉冲时间重心以及有效宽度等参量的解析表达式,分析表明,啁啾使得载波相位比无啁啾的情况提前起作用了,即啁啾在很大程度上增大了载波相位发挥作用所对应的脉宽范围。
