Abstract

Perfeccionamientos en sistema de radar, especialmente del tipo de más de un canal receptor, caracterizados por comprender medios para introducir un impulso de señales en un punto predeterminado de un canal receptor durante un corto periodo, en el llamado "tiempo muerto", antes de la transmisión de un impulso de radar medios para derivar dicho impulso de señales de dicho canal, después de pasar a través de la parte de éste cuya ganancia ha de controlarse automáticamente, medios para comparar el impulso de señales así derivado, con una señal de referencia y medios para utilizar la resultante de la comparación con objeto de controlar automáticamente la ganancia de dicho canal a fin de mantenerla en un valor predeterminado.
