Not confined to a certain point,such as waveform,this paper systematically studies the low-intercept radio frequency(RF)stealth design of synthetic aperture radar(SAR)from the system level.The study is carried out from two levels.In the first level,the maximum low-intercept range equation of the conventional SAR system is deduced firstly,and then the maximum low-intercept range equation of the multiple-input multiple-output SAR system is deduced.In the second level,the waveform design and imaging method of the low-intercept RF SAR system are given and verified by simulation.Finally,the main technical characteristics of the lowintercept RF stealth SAR system are given to guide the design of low-intercept RF stealth SAR system. 展开更多

从侦察接收机的角度,推导了超宽带雷达信号的低截获概率因子。由于LPI雷达具有大时间带宽积,故超宽带雷达具有高处理增益而抵消侦察接收机在侦察距离上的优势。推导了临界距离条件下侦察接收机的输出信噪比,并与能量检测所需信噪比进行... 从侦察接收机的角度,推导了超宽带雷达信号的低截获概率因子。由于LPI雷达具有大时间带宽积,故超宽带雷达具有高处理增益而抵消侦察接收机在侦察距离上的优势。推导了临界距离条件下侦察接收机的输出信噪比,并与能量检测所需信噪比进行了比较,最后得出:当超宽带雷达带宽大于1.6 GHz时,超宽带雷达在频域上表现为低截获性。 展开更多
