Abstract
The monitoring of the various radar sites is performed with automatic test equipment located at each site. Data from various sensors and monitoring points within the radar is acquired locally and transferred to the ROCC through RF and telecommunications links. Acquired data consists of multiple data streams, tables, and other status reports presented on computer monitors, stored in RCG local memory and on disk, and archived on tape or printed on paper. Of all these reports, one is a bitmap providing a graphical status representation of the multiple electronic components within the radar. The bitmap provides valuable information on the radar functional status and on the corrective actions to be taken. The bitmaps are received at the ROCC and stored in RCG local memory. The memory has a first in first out buffer that can hold up to 64 bitmaps per site. Once the buffer reaches its full capacity, bitmaps are lost. This can be a major inconvenience if an event must be traced back in which case there is a significant probability that the required bitmap is lost if the request to print comes too late. The Department of National Defence is interested in logging all bitmaps at the ROCC for future retrieval. This would eliminate the loss of critical information and simplify diagnostics of the radar. The goal of this document is to explore the various ways in which the bitmap data could be logged and formulate recommendations.
