While for decades radars in the 94-GHz region of the electromagnetic spectrum were mainly developed for military applications, nowadays a range of other applications mainly concerning security and safety can be served by miniaturizes millimeterwave radars. The technology is considerably different from that used in the past. One terminal devices like Gunn- and IMPATT oscillators with limited bandwidth...
Based upon most recent advances in millimeterwave technology, especially monolithic integrated low noise or medium power HEMT amplifiers and an integrated receiver containing an LNA, Mixer and IF Amplifier, a miniaturized experimental radar at 94 GHz was designed with the aim to be used on board of a remotely piloted model aircraft. This highly advanced front-end technique was combined with of-the-shelf...
An experimental radar operating simultaneously at 10 GHz, 35 GHz, 94 GHz and 220 GHz has been developed, which is capable to deliver an instantaneous bandwidth of 4000 MHz at the lower frequency bands and 8000 MHz at 220 GHz. The radar is of FM-CW type and uses a chirp modulation. Two types of application have been envisaged, both to determine the scattering centre distributions of targets, one using...
Concealed weapon detection based on passive millimeter wave imaging requires a high spacial resolution to achieve useful output. In order to meet this requirement while decreasing the overall imaging time, the approach presented here employs a mechanically scanned focal plane array at 94 GHz. In this paper, details about a four-channel scanning radiometer setup are given using a novel compact W-band...
