Design of an Improved Weather Contouring Device.

Abstract

A prototype weather contouring device was developed and built by the National Aviation Facilities Experimental Center (NAFEC) to aid in the preparation of procurement specifications. The device uses the new concept of contour symbol generation to produce lines, shaded areas, or other symbols necessary to generate contours of weather intensity. Unlike former techniques, this device generates homogeneous lines and is easily programmable for other formats. The device can provide dots or other symbols to the more intense side of a weather contour line clearly aiding the interpretation of the weather display. The device is designed to take advantage of digital signal transmission tecniques for the transmission of up to six levels of weather intensity. Any two of these six levels can be simultaneously displayed. The device was designed for those applications where plan position indicator (rho-theta) format is desired or necessary. Tests indicate that the device can generate contours which are exceptionally smooth and stable and are well suited to use in the air traffic control system. (Author)
