Target acquisition, locating and tracking system

摘要: In accordance with the present invention there is provided a monitoring system that monitors and locates objects such as airplanes other vehicles on runways, taxiways, or preprogrammed areas. The utilizes minimum of three transmitters for generating diffusion field two receivers which detect displacements in field. are coupled computer calculates position object causing displacement area to be monitored divided into grids programmed onto computer, moving cause changes signal received by conveyed compared grid indicate location changes.
