Design-oriented EMC analysis of electrical system of airborne optoelectronic pod

The paper focuses on the electromagnetic environment characteristics of airborne optoelectronic pod and conducts targeted electromagnetic compatibility design. An in-depth analysis was conducted from three aspects: interference sources, transmission paths, and sensitive devices. Elaborate on the use of grounding, electromagnetic shielding, filtering methods, a s well as specific measures for electromagnetic protection of interface circuits, power boards, single boards, and cables to reduce conducted and radiated interference. Finally, the electromagnetic interference problem was analyzed and solved through an example.
