Abstract

método de transmissão de sinal e aparelho. este pedido fornece um método de transmissão de sinal e aparelho, que se refere a uma tecnologia de escuta de interferência de radar cooperativa, e pode ser aplicado ao campo de direção autônoma, direção inteligente, ou direção não tripulada. um método de transmissão de sinal inclui: um aparelho de detecção de radar seleciona uma banda de frequência de transmissão a partir de uma primeira banda de frequência predefinida ou pré-especificada. a primeira banda de frequência é pré-dividida em m bandas de subfrequência, e a banda de frequência de transmissão inclui n bandas de subfrequência nas m bandas de subfrequência, em que uma largura de banda da banda de frequência de transmissão é maior que ou igual a uma largura de banda operacional do aparelho de detecção de radar. uma soma de larguras de banda de quaisquer n-1 bandas de subfrequência nas n bandas de subfrequência é menor que a largura de banda operacional do aparelho de detecção de radar. em outras palavras, a soma das larguras de banda de quaisquer n-1 bandas de subfrequência não pode atender a um requisito para transmissão de sinal, em que n e m são números inteiros positivos. desta forma, seleção da banda de frequência de transmissão do radar pode ser padronizada, e randomização total pode ser evitada. além disso, uma quantidade mínima de bandas de subfrequência é usada para transmitir um sinal e, consequentemente, utilização de recurso é melhorada, e interferência entre aparelhos de detecção de radar é reduzida.
