Enrichment (EN)

Disambiguation: Filter Factor in this context refers to radar filtering thresholds in military air defense, distinct from photographic filter factors or general engineering filters.

Filter Factor is a threshold parameter used in military radar and air defense systems to selectively exclude or include objects based on specific operational characteristics such as speed, altitude, and radar cross-section (size). Developed during the Cold War to filter out clutter and focus on known threat profiles (primarily Soviet bombers and ballistic missiles), filter factors were historically configured to exclude anything too slow, too high, too low, or moving at speeds inconsistent with conventional aircraft. In the context of UAP detection and the Department of War archive, Filter Factors became operationally significant after 2023 when NORAD adjusted these parameters to improve sensitivity to high-altitude, low-speed, and small-signature objects, revealing previously undetected anomalies in US airspace.

Desambiguação: Filter Factor in this context refers to radar filtering thresholds in military air defense, distinct from photographic filter factors or general engineering filters.

Filter Factor é um parâmetro de limiar usado em sistemas militares de radar e defesa aérea para excluir ou incluir seletivamente objetos com base em características operacionais específicas, como velocidade, altitude e seção transversal de radar (tamanho). Desenvolvido durante a Guerra Fria para filtrar ruído e focar em perfis de ameaça conhecidos (principalmente bombardeiros soviéticos e mísseis balísticos), os fatores de filtro eram historicamente configurados para excluir qualquer coisa muito lenta, muito alta, muito baixa ou movendo-se em velocidades inconsistentes com aeronaves convencionais. No contexto de detecção de UAP e do arquivo do Departamento de Guerra, os Fatores de Filtro tornaram-se operacionalmente significativos após 2023, quando a NORAD ajustou esses parâmetros para melhorar a sensibilidade a objetos de alta altitude, baixa velocidade e assinatura pequena, revelando anomalias previamente não detectadas no espaço aéreo dos EUA.
