Radar Field Analyser - RFA641 Edition Date: 28-Feb-18
Since the software doesn’t distinguish between single and multiple derived HPDs all other features
such as OTD calculation keep on working correctly.
3.3.5. User Defined OTD Limits
The OTD Limits section displays the OTD Limits applied to the calculated antenna parameters. Whenever
the program is evoked, it will first read the limits from an OTD Definition file. The OTD error messages will
be displayed accordingly.
OTD Definition files are present in the GENERAL\OTD subdirectory of the CAMPAIGN directory. Currently
the file ‘EC.OTD’ is the only file available. This file contains the EC defined parameter limits according to the
description in Annex 1: Critical Parameters of SSR Antennas.
The loaded OTD definition file is indicated on the program front panel.
