A millimetric wave imaging device includes: a lens antenna; a polygon mirror; a receiving portion; a scanning unit; and an image data generating unit. The receiving portion receives millimetric wave radiated from an object, transmitted through the lens antenna, and reflected on a mirror surface of the polygon mirror rotated by the scanning unit to detect a signal level of the millimetric wave. The image data generating unit generates image data representing an object image by receiving a detection signal from the receiving portion while driving the polygon mirror through the scanning unit.

A navigation system for vehicle is provided with a route determination process by which a route is determined intersection by intersection. When a starting point and driving direction are input, a road is selected, determined as the route to take, and indicated as the route on a display. A further road, of the same category as the road determined, is determined as a further route. Automatic route determination is thus consecutively effected from the starting point toward a destination. When cancellation of the determined route is instructed, the route is canceled intersection by intersection. When the cancellation is finished or if no road can be selected, the navigation system resumes its operation recognizing the end of the determined route newly as starting point.

A navigation system for motor vehicles determines a pie-shaped sector zone for triggering an indication of a route intersection on a displayed road map. The zone is defined by a pie-shaped sector of a circle having the intersection at its center, and provided with a radius determined with respect to the velocity of the vehicle. When the vehicle enters the zone corresponding to the vehicle's velocity, it is determined that the vehicle is approaching the intersection, and a next intersection to be passed by the vehicle is indicated on the road map. The driver can thus be guided along a predetermined route.
