Abstract

método e sistema para cancelamento de padrão de porta de correr na detecção de metal. um método e sistema para reduzir os efeitos da interferência do sinal das portas de metal em um sistema de detecção de metal são revelados. o sistema inclui um transmissor operável para transmitir um sinal de interrogação que é usado para detectar objetos de metal transitórios dentro da região de detecção, um receptor operável para receber os sinais instantâneos que representam as pertubações do campo eletromagnético durante a operação do sistema de detecção de metal e incluem pertubações do campo eletromagnético atribuídas ao movimento das portas de metal. o sistema também inclui um módulo de detecção de metal que determina uma forma de onda resultante representando a diferença entre os sinais instantâneos recebidos durante a operação do sistema de detecção de metal e um padrão gravbado de sinais representando as pertubações do campo eletromagnético causadas por um padrão de movimento das portas de metal na região de detecção quando um objeto metálico transitório não está presente. o padrão de gravação é cancelado da forma de onda resultante deixando somente os sinais dos objetos de metal transitórios.
