Abstract

EN ADICION AL PROCESADOR DE DETECCION DE FILTRO AJUSTADO (44) USADO CONVENCIONALMENTE, SE UTILIZA UN PROCESADOR DE SEÑAL INCOHERENTE (46) QUE ABARCA UN ALCANCE TRANSVERSAL DE FILTRO DE ENERGIA (28) Y UN ALCANCE HORIZONTAL DE FILTRO DE ENERGIA , POR ESA RAZON SE COMBINA EL USO DE AMBOS PROCESADORES EL DE SEÑAL COHERENTE Y EL DE SEÑAL INCOHERENTE (44, 46). EL FILTRO DE ENERGIA DE ALCANCE TRANSVERSAL (28) DETECTA OBJETOS QUE SE CARACTERIZAN POR UNA RESPUESTA DE ORIENTACION CERCANA; MIENTRAS EL FILTRO DE ENERGIA DE ALCANCE HORIZONTAL (32) DETECTA OBJETOS CARACTERIZADOS POR RESPUESTA DE ALCANCE CERCANO. LOS ACONTECIMIENTOS DE DETECCION PROVINIENTES DEL PROCESADOR DE SEÑAL INCOHERENTE (46) SON VISUALIZADOS (36) EN UN COLOR SUAVE PARA PREVENIR LA DISTRACCION SOBRE ACONTECIMIENTOS DE VISUALIZACION PRIMARIA Y PARA REDUCIR LA PROPORCION DE FALSA ALARMA POR PERMITIR AL OPERARIO DE SONAR CONSIDERAR LOS ACONTECIMIENTOS EN EL CONTEXTO DE LIMITES NATURALES.
