Concept
A threshold parameter in military radar systems that selectively excludes or includes objects based on operational characteristics (speed, altitude, radar cross-section), historically configured to filter out non-conventional threats and reduce detection clutter.
Um parâmetro de limiar em sistemas militares de radar que exclui ou inclui seletivamente objetos com base em características operacionais (velocidade, altitude, seção transversal de radar), historicamente configurado para filtrar ameaças não convencionais e reduzir ruído de detecção.
