- The range Doppler clutter characteristics are analyzed in detail in this paper. In the case of LPRF,a novel space time adaptive processing approach based on range Doppler compensation is proposed to suppress the clutter for bistatic AEW radar. 深入分析了双基地机载预警雷达杂波距离多普勒特性 ;进而提出了一种基于距离多普勒补偿的空时二维自适应处理方法 .
- Under the condition of zero Doppler frequency shifts,this kind of"waveform pair"is equivalent to polyphase Barker coded waveform at costs of a small amount of loss in signal-to-noise ratio and widening of the bottom of mainlobe. 在零多普勒频移条件下,这类“波形对”能以少量信噪比损失为代价使脉压输出波形的主旁瓣比等于码序列的长度,也就是说,从主旁瓣比的角度讲,这类“波形对”可以等效为相应长度的多相巴克码波形。
