Abstract

CON EL OBJETO DE MEDIR LA DISTANCIA DE UN BLANCO, EN UN RADAR DOPPLER DE IMPULSOS DE RECUENCIA AGIL, CON ALTA FRECUENCIA DE REPETICION DE IMPULSOS (HPRF) EN EL AMBITO DE VELOCIDAD UNIVOCA, SE TRANSFORMARA A LA GAMA DE FRECUENCIAS LA SEÑAL COMPLEJO DE TIEMPO, QUE SE INDICA MEDIANTE LAS SEÑALES ACUSTICAS DENTRO DE UN INTERVALO DE PROCESAMIENTO (CPI). EL ESPECTRO TRANSFORMADO SE MULTIPLICARA CON UNA FUNCION DE (FILTRO) PASABANDA CUYA FRECUENCIA NOMINAL ES LA FRECUENCIA DOPPLER DEL BLANCO. LUEGO EL PRODUCTO SE RETRANSFORMARA EN UNA SEÑAL DE TIEMPO. LA SEÑAL DEL IMPORTE DE ESTA SEÑAL DE TIEMPO RETRANSFORMADO, MUESTRA CLARAMENTE UN BORDE DEL IMPULSO ASCENDENTE, DE CUYO TRANSCURSO PUEDEN ESTIMARSE LA DURACION DE RECORRIDO DE LAS SEÑALES ACUSTICAS Y DE ESTE MODO TAMBIEN LA DISTANCIA DEL BLANCO. RESULTAN VENTAJAS ESPECIALES PARA UN RADAR DOPPLER DE IMPULSOS ON VARIOS APARATOS EMISORES Y RECEPTORES DE FRECUENCIA AGIL, QUE FUNCIONEN SIMULTANEAMENTE EN FRECUENCIAS DIFERENTES CON UN ESCALONAMIENTOTEMPORAL DE SUS MOMENTOS DE CAMBIAR LA FRECUENCIA
