Abstract

Perfeccionamientos en sistemas de radar caracterizados por utilizarse la transmisión de señales de impulsos periódicos y la recepción de señales devueltas por los objetos circundantes, que se aplican a un dispositivo de aprovechamiento y por disponerse medios para producir una señal de control sincronizada con el periodo de las señales pulsatorias y que tiene durante el intervalo entre impulso transmitidos, magnitudes de valor comprendido entre límites predeterminados, correspondientes al nivel de la señal confusa instantánea recibida y medios de control para alterar la sensitividad de respuesta de dicho dispositivo, de acuerdo con la señal de control.
