Design of synthetic aperture radar low-intercept radio frequency stealth

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 low-intercept RF stealth SAR system are given to guide the design of low-intercept RF stealth SAR system.
