European Microwave Outages (Blackout of German Scope Comm Links,October thru February 76).

摘要

The operation and maintenance functions for the Defense Communications System (DCS) are performed by the military departments. The Air Force Communications Service (AFCS) is responsible for the engineering, installation, operations, and maintenance for approximately sixty percent of the wideband (line-of-signt and tropospheric scatter) systems within the DCS. During the period between October 1975 and February 1976, several links of the DCS wideband line-of-sight (LOS) system in Central Germany experienced at least one propagation outage. During this time, the Air Force links in the system suffered outage time ranging from 22 minutes to 42 hours. These propagation outages were attributed to temperature inversions. This report will outline the characteristics of the links that failed, state the difficulties involved with making decisions based on existing data and give AFCS's initial evaluation and potential solutions to the problem. This report will also outline the need for a more in-depth study of the problem. (Author)
