Abstract

Perfeccionamientos en sistemas de radar, caracterizado por comprender un transmisor, un oscilador de localización a el conectado, para modular la frecuencia de aquél, un generador de oscilaciones de fluctuación, conectado a oscilador de localización, para corregir o modular, en frecuencia, las oscilaciones de éste, un receptor de señales de eco, un mezclador para mezclar las señales recibidas con señales derivadas directamente del transmisor, medios para extraer de la resultante de dicha mezcla, una componente de la frecuencia de fluctuación , medios para comparar la componente extraída, con una frecuencia de fluctuación medios para comparar la componente extraída, con una frecuencia de referencia obtenida de dicho generador, para producir una señal de error, y medios para utilizar esta señal de error a fin de controlar la frecuencia media del oscilador de localización, con objeto de mantenerlo dirigido hacia el blanco u objetivo desde el cual se reflejan las señales de eco.
