Abstract
SE DERIVAN DE LAS SEÑALES SUMA Y DIFERENCIA DE UN RECEPTOR DE RADAR MONOIMPULSO UN PAR DE DIAGRAMAS CARACTERISTICOS QUE DE MANERA RAPIDA Y FIABLE, ESDECIR, AMBIGUAMENTE, INDICA CUANDO UN BLANCO QUE ES RASTREADO O SEGUIDO SE MUEVE FUERA DEL CENTRO DEL HAZ PRINCIPAL DE LA ANTENA. LAS SEÑALES SUMA Y DIFERENCIA SE COMBINAN EN CUADRATURA DE FASE PARA FORMAR UNA PRIMERA SEÑAL DE DIAGRAMA CARACTERISTICO DE VECTOR. LAS SEÑALES SUMA Y DIFERENCIA SE COMBINAN EN CUADRATURA DE FASE PARA FORMAR UNA SEGUNDA SEÑAL DE DIAGRAMA CARACTERISTICO DE VECTOR DE MANERA QUE LA DIFERENCIA DE FASE ENTRE LAS SEÑALES DE DIAGRAMA CARACTERISTICO VARIA CON LA AMPLITUD DE LA SEÑAL DIFERENCIA. LOS DIAGRAMAS CARACTERISTICOS PRIMERO Y SEGUNDO SE COMPARAN PARA DETECTAR LA DIFERENCIA DE FASES ENTRE ELLOS. SE UTILIZAN DIAGRAMAS CARACTERISTICOS CONMUTADOS PARA DETERMINAR LA DIRECCION DE DESPLAZAMIENTO DE BLANCO DESDE LA MIRA DE LA ANTENA Y/O VERIFICAR LA EXACTITUD DE LA INDICACION DE SALIDA DE HAZ.
