Digitized Radar Data Compressor.

摘要

The data compressor (DACOMP) is a special-purpose device designed specifically to increase radar data recording capabilities at air route traffic control centers (ATRCC's). The DACOMP accomplishes this by compressing the number of channels each radar occupies prior to recording, thereby reducing the number of tape tracks required for each radar. The three 2400 bit-per-second channels of a digitized radar are compressed onto one high-speed (9375 bit-per-second) channel. Because of the threefold reduction in recording track requirements, use of DACOMP's will enable ARTCC's to record information from an increased number of radar sites on the recorders that are available to them. This report explains the installation, use, theory of operation, and maintenance of the DACOMP. (Author)
