Abstract

método, aparelho, e, mídia não transitória legível por computador para armazenar código. a presente invenção se refere a métodos, sistemas e dispositivos para rastreamento de sinal de evento passado. em alguns exemplos, um sistema pode receber sinais de elemento de alimentação que correspondem a um conjunto de elementos de alimentação de uma antena. para suportar uma missão primária ou em tempo real, o sistema pode processar os sinais de elemento de alimentação de acordo com uma primeira configuração de formação de feixes para gerar sinais de feixe pontual, que podem incluir comunicações agendadas para os respectivos feixes pontuais. para suportar uma missão retroativa ou de busca, o sistema pode também armazenar os sinais de elemento de alimentação durante algum tempo. com base em uma determinação para procurar por um sinal-alvo a partir de um local-alvo dentro de uma área de cobertura da antena, o sistema pode processar os sinais de elemento de alimentação armazenados de acordo com uma segunda configuração de formação de feixes para gerar um sinal de feixe pontual correspondente ao local-alvo, e avaliar o sinal de feixe pontual quanto à presença do sinal-alvo.
