| Popis: | In this chapter, the general principle and several systems for millimeter-wave sensors were discussed, and the state of development was also described. Furthermore, a 94-GHz-band passive millimeter-wave imaging sensor developed by Fujitsu Laboratories was shown in detail. The authors developed an ultra low-noise-receiver MMIC, and integrated it with a compact receiver module. The authors also realized a high-density imaging array to obtain millimeter-wave images in a short time. The considerations and the design method can also be used for other applications such as a broadband radio communication systems and radar. |
