Summary:An experimental radar at 220GHz has been developed, which is capable of delivering an instantaneous bandwidth of 8000MHz. The solid-state radar uses an FM-CW waveform. The development is based on experience with a 94GHz broadband measurement radar. The data undergo an ISAR imaging process to derive high-resolution scattering centre distributions for targets measured in tower/turntable configuration. High-resolution processing algorithms have been developed, which result in scattering centre distributions with a resolution better than 2cm at ranges of and exceeding 200m. The radar will be used for investigations on target signatures of small objects for stand-off detection of concealed weapons and other threat material.
