Abstract
APARATO DE DETECCION DE OBJETO (4) INCLUYE UN CONJUNTO TRANSMISOR (44) Y UN CONJUNTO RECEPTOR (10). EL CONJUNTO RECEPTOR INCLUYE UN ELEMENTO RECEPTOR (12) QUE TIENE UNA ABERTURA DE ENTRADA (16) PARA RECIBIR UNA RADIACION ELECTROMAGNETICA QUE SE REFLEJA DESDE UN OBJETO. EL ELEMENTO RECEPTOR INCLUYE ADEMAS UNA ABERTURA DE SALIDA (24) Y UNA SUPERFICIE CURVADA (22) DISPUESTA RESPECTO DE LA ABERTURA DE ENTRADA PARA REFLEJAR SUSTANCIALMENTE TODA LA RADIACION ELECTROMAGNETICA (A, B, C), QUE SE REFLEJA DESDE UN OBJETO A UNA DISTANCIA EXCESIVA DE UNA DISTANCIA DE INTERES, A LA ABERTURA DE SALIDA. UN PRIMER DETECTOR DE RADIACION (14) ESTA DISPUESTO EN LA ABERTURA DE SALIDA PARA RECIBIR LA RADIACION DEL OBJETO REFLEJADA SOBRE ESTA Y PARA GENERAR UNA PRIMERA SEÑAL ELECTRICA. UN SEGUNDO DETECTOR DE RADIACION (30) ESTA DISPUESTO EN UN LUGAR SOBRE EL CONJUNTO RECEPTOR PARA RECIBIR LA RADIACION DEL OBJETO REFLEJADA SOBRE ESTE DESDE UN OBJETO A UNA DISTANCIA QUE ESTA DENTRO DE LA DISTANCIA DE INTERES. EL APARATO COMPRENDE ADEMAS LA CIRCUITERIA (32, 34, 36, 37, 38, 39) PARA COMBINAR LA PRIMERA SEÑAL ELECTRICA CON LA SEGUNDA SEÑAL ELECTRICA PARA ELIMINAR SUSTANCIALMENTE UN COMPONENTE DE LA PRIMERA SEÑAL ELECTRICA QUE SE DEBE A LA RADIACION ELECTROMAGNETICA QUE SE REFLEJA DESDE UN OBJETO DENTRO DE LA DISTANCIA DE INTERES.
