Terahertz imaging technology plays an important role in the applications of high-resolution imaging and detection of small targets. The imaging system design is optimized with step-frequency signal in 220GHz frequency band as well as the imaging algorithms are conducted. In order to get high resolution, the 220GHz system is designed and realized with stepped frequency. the technology of high-resolution...
In high range-resolution radar system, in order to achieve high range resolution, signals having wide bandwidth are required. The higher the working frequency is used, the more bandwidth is got. Stepped frequency waveforms in millimeter wave band is available to get one-dimension multiple scattering centers distribution or the profile, furthermore, two dimension multiple scattering centers distribution...
