Abstract :
An experimental radar at 94 GHz has been developed, which is capable of delivering an instantaneous bandwidth of 4 GHz. The radar uses an FM-CW waveform and is fully solid state. The data undergo an ISAR imaging process to derive high resolution scattering centre distributions for targets measured in tower/turntable configuration. The high resolution processing has to rely on an appropriate polar reformatting procedure, which is not necessary for ISAR imaging at millimetre waves with resolutions worse than 10 cm.
