Electronic Countermeasures (ECM) is a military technology and electronic warfare doctrine designed to disrupt or deceive enemy radar, sonar, and other detection systems. Originating in the early 20th century and extensively developed during World War II, ECM employs three primary methods: jamming (transmitting noise to overwhelm receivers), deception (creating false radar echoes or signals), and target modification (using chaff or radar-absorbing materials). Modern ECM systems are integrated into military aircraft, ships, and ground-based units, and serve as critical defensive tools to prevent aircraft from being tracked by search radars or targeted by guided missiles. The technology remains a fundamental component of military electronic warfare doctrine across NATO and other armed forces.

Contramedidas Eletrônicas (ECM, do inglês Electronic Countermeasures) é uma tecnologia militar e doutrina de guerra eletrônica projetada para interromper ou enganar sistemas de detecção inimigos, como radar e sonar. Originária do início do século XX e extensivamente desenvolvida durante a Segunda Guerra Mundial, a ECM emprega três métodos principais: jamming (transmissão de ruído para sobrecarregar receptores), deception (criação de ecos de radar ou sinais falsos) e modificação de alvo (uso de chaff ou materiais que absorvem radar). Sistemas modernos de ECM são integrados em aeronaves militares, navios e unidades baseadas em terra, e servem como ferramentas defensivas críticas para evitar que aeronaves sejam rastreadas por radares de busca ou alvo de mísseis guiados. A tecnologia continua sendo um componente fundamental da doutrina de guerra eletrônica militar em toda a OTAN e outras forças armadas.
