Abstract

UN SISTEMA DE RADAR (20) INCLUYE UN RECEPTOR DE RADAR (22) QUE SUMINISTRA LA AMPLITUD Y LA POSICION ANGULAR DE UNA PLURALIDAD DE SEÑALES DE RETORNO. UN ORDENADOR FORMA UNA FUNCION DE PRUEBA DE LAS AMPLITUDES Y DE LAS POSICIONES ANGULARES DE LA PLURALIDAD DE SEÑALES DE RETORNO Y COMPARA LA FUNCION DE PRUEBA CON UN VALOR LIMITE. LOS RETORNOS ASOCIADOS CON LA FUNCION DE PRUEBA CUYO VALOR ES IGUAL O MAYOR QUE EL VALOR LIMITE SON DETERMINADOS COMO OBJETIVOS (26), Y AQUELLOS CON VALORES INFERIORES SON CONSIDERADOS ECOS PARASITOS.
