Artech House Intersystem EMC Analysis, Interference, and Solutions

Electromagnetic compatibility (EMC) issues need to be an initial consideration in design and deployment of electronic transmitters or receivers, or in deployed systems containing both. This book provides methodologies for defining EMC requirements for the device, platform, site, and arena levels and techniques for performing predictions and calculations to achieve electromagnetic compatibility. While the book considers all transmitting and receiving systems and devices, it emphasizes military applications. Examples of the occurrence of electromagnetic problems are interference when devices are physically close and operating at the same, or similar, frequencies. In order to address this, the authors discuss several new approaches in mathematical development, such as the calculation of probability of interference based on frequency difference between two devices and the interference probability due to pulse to pulse interference. In theory, all the devices parameters should be available for analysis, but in practice, missing data is not uncommon. The book aims to define default values that allow the performance of EMC analysis in cases where the data is missing, such as antenna patterns, intercardinal antenna gain and near field approximations. The treatment of EMC problems is quite mathematical and technical, but some chapters are intended for operational personnel such as system analysts, project managers and operations researchers.
