Abstract

Un sistema de radiolocalización que comprenda el medio de transmitir desde una primera estación ondas de radiofrecuencia cuya frecuencia varie cíclicamente; en una segunda estación un medio que comprenda un repetidor para recibir dichas ondas de radiofrecuencia y transmitir de allí ondas de radiofrecuencia y correspondientes que varíen de frecuencia; el medio en dicha primera estación de recibir las ondas transmitidas de dichas segunda estación y otras ondas que varíen de frecuencia de acuerdo con las variaciones de frecuencia de las ondas procedentes de dicho medio de transmisión mencionado en primer término; y en dicha primera estación un medio que reacciones con dichas ondas recibidas y dichas otras ondas para comparar la frecuencia de dichas ondas recibidas y dicha energía a efecto de determinar la distancia que medie entre dichas estaciones primera y segunda.A radiolocation system that includes the means of transmitting radio frequency waves from a first station whose frequency varies cyclically; in a second station a means comprising a repeater to receive said radio frequency waves and transmit from there radio frequency and corresponding waves that vary in frequency; the means in said first station of receiving the waves transmitted from said second station and other waves that vary in frequency according to the frequency variations of the waves coming from said first-mentioned transmission medium; and in said first station a means that reacts with said received waves and said other waves to compare the frequency of said received waves and said energy in order to determine the distance between said first and second stations.
