频率分集式二相编码信号的波形设计及处理研究

On Waveform Design of Frequency Diversity Biphase Coded Signals

提出以频率分集的短码代替长码的雷达波形设计和信号处理方法,改善了大压缩比二相编码信号的多普勒容限和近距探测性能。还提出了分别利用非相参积累和非相干加权处理进一步提高频率分集信号主副(?)比的方法。给出了压缩比为190的波形设计实例和信号处理的实验结果。

A new method of radar waveform design and signal processing,which replace:the long code with frequency diversity shorter codes,is investigated to improve the Doppler tolerance and near-range sounding of biphase coded signals with large compression ratio.In addition,noncoherent integration and weighted processing are introduced separately to furtherly raise the peak ratio of mainlobe to sidelobe (RMS) of frequency diversity signals.At The compression ratio of 190,waveform design and signal processing hardware experiment are given.
