Space engineering - Electromagnetic compatibility handbook

The objective of this EMC Handbook is to point out all the issues relevant to space systems EMC, to provide a general technical treatment and to address the interested reader to more thorough and in-depth publications.
NOTE: It is possible to find fundamental and advanced treatment of many aspects related to EMC: many universities offer courses on EMC and a large number of textbooks, papers and technical documents are available. Therefore replicating in this Handbook the available knowledge is impractical and meaningless.
Emphasis is given to space systems EMC design, development and verification, and specifically to the practical aspects related to these issues.
NOTE: This has been possible thanks to the collaboration of space industry, especially on items which are not textbook issues and whose solution needs the widespread experience gained in large number of projects.

Vesoljska tehnika - Priročnik o elektromagnetni združljivosti

Cilj tega priročnika o elektromagnetni združljivosti je opozoriti na vsa vprašanja z zvezi z elektromagnetno združljivostjo vesoljskih sistemov, zagotoviti splošno tehnično obravnavo ter usmeriti zainteresiranega bralca k temeljitejšim in poglobljenim publikacijam.
OPOMBA: Tematika elektromagnetne združljivosti je izčrpno obravnavana s temeljnih in naprednih vidikov: številne univerze ponujajo tečaje o elektromagnetni združljivosti, na voljo pa je veliko učbenikov, člankov in tehničnih dokumentov. Zato ponavljanje znanja, ki je že na voljo, v tem priročniku ni praktično in smiselno.
Poudarek je na projektiranju, razvoju in potrjevanju elektromagnetne združljivosti vesoljskih sistemov ter zlasti na praktičnih vidikih, povezanih s temi vprašanji.
OPOMBA: To je mogoče na podlagi sodelovanja vesoljske industrije, zlasti pri zadevah, ki niso učbeniška vprašanja in katerih rešitev zahteva obsežne izkušnje, pridobljene pri velikem številu projektov.
