Abstract

SE DESCRIBE UN ESTRECHADOR DE MATRIZ VARIABLE PARA CONSEGUIR UNA CONFORMACION EFICIENTE DE IMPULSOS DE RADAR PARA HACER AVANZAR LAS FORMAS DE LAS ONDAS DEL RADAR COMO UN BARRIDO DE IMPULSOS O COMO UN DOPPLER DE MONOIMPULSOS. EN EL PRINCIPIO DEL IMPULSO SOLAMENTE UNOS POCOS ELEMENTOS (22), ESPARCIDOS SOBRE LA MATRIZ (20) SE ENCUENTRAN ACTIVADOS. LA AMPLITUD EFECTIVA PUEDE CONTROLARSE CON PRECISION A CAUSA DE QUE CADA ELEMENTO (22) ESTA TANTO FUERA COMO EN SATURACION. LA ALTA EFICIENCIA SE MANTIENE A CAUSA DE QUE EL ESTADO DE APAGADO DE CADA ELEMENTO, ES LO SUFICIENTEMENTE LARGO COMO PARA QUE NO SE CONSUMA LA ENERGIA PRIMARIA.
