Abstract

This paper describes various measures that have been taken to ensure Electromagnetic Compliance of Man Machine Interface Computer used in Fire Control Radar System as per MIL-STD-461E. It covers evaluation and reduction of radiated emission from the unit under test. Even with basic design techniques in place non-conformance to the standard were observed. The potential sources of Electromagnetic Interference were identified, analyzed and removed. Detailed discussion on these solutions is presented in the paper. With these solutions in place an average reduction of 10dBuv/m in the noise level is observed. Radiated measurements demonstrate the effectiveness of these recommendations.
