Title (EN) CW PHASE-COMPARISON SECONDARY RADAR SYSTEM
(FR) SYSTEME RADAR SECONDAIRE A COMPARAISON DE PHASES CW
Abstract: front page image
(EN)A distance measuring system in which a first station (figure 1) radiates a modulated carrier wave and a second station (figure 2) receives that wave, and retransmits the modulation on a carrier wave back to the first station, which compares the phases of the original and received modulations. The second station includes a digital counter (19) which accumulates clock pulses (22) denoting the period of the modulation and a second counter is (26) incremented and decremented to reproduce the modulation for retransmission thereof.
(FR)Un systeme de mesure de distances dans lequel une premiere station (Fig. 1) emet une onde porteuse modulee et une seconde station (Fig. 2) recoit cette onde, et retransmet la modulation sur une onde porteuse en la renvoyant a la premiere station, qui compare les phases des modulations d'origine et recue. La seconde station comprend un compteur numerique (19) qui accumule des impulsions d'horloge (22) indiquant la periode de la modulation et un second compteur recoit (26) des increments et des decrements pour reproduire la modulation en vue d'en effectuer la retransmission.
