频率步进太赫兹雷达的一维高分辨距离像
One-dimensional high range resolution profile of terahertz radar
摘要
Abstract
Stepped frequency signal is one of the most extensively used radar signal for high range resolution,which is commonly used in radar target recognition. The wavelength of Terahertz signal is shorter than that of the microwave, so it is easy to realize the high range resolution. The method how stepped frequency THz radar to obtain the one-dimensional distance image is introduced,and the principle of High Resolution Range Profiles(HRRP) of step frequency radar is analyzed. The 0.2 THz stepped frequency radar system is introduced. Finally,the HRRP of the THz radar are realized by the simulation in Matlab. The simulation results show that the stepped frequency THz radar can reach centimeter-scale high resolution on stationary targets. For moving targets,there exist distance divergence and coupling shift. The higher the speed,the greater the distortion.关键词
