Abstract
Procedimiento de recepción con varias antenas receptoras individuales, en que a una señal de salida de antena se le imprima una modulación de fases, se suman las señales de antena y la señal de sumas se demodula según amplitud, caracterizado porque - a las distintas señales de salida de antena se les imprime encima una modulación auxiliar, en forma de una modulación de fases y/o de amplitudes, mediante una señal de modulación auxiliar, - la señal de sumas, amplificada y seleccionada en una conexión de recepción, se demodula en un demodulador de frecuencia y de amplitudes, según el importe y la frecuencia y/o la fase, - la señal de modulación auxiliar, desde la que se extrae por filtrado la señal demodulada, con ayuda de demoduladores sincrónicos, se determina la parte real y la parte imaginaria de la señal de antena individual respecto a la señal de sumas y de ello se derivan la posición de fase y la contribución de amplitudes de la señal individual respecto a la señal de sumas y - las fases y/o las amplitudes de las señales individuales de alta frecuencia, en dependencia de la posición de fases determinada, en cada caso, se modifican en la dirección hacia contribución de amplitudes óptima.
