Apparatus for measuring the power of intense microwave pulses comprises a
conducting track (3) formed on an insulating substrate (1, 2) and coupled to
radiation from a remote source (10) via an antenna (7) and transmission line
(6). The subsequent heating of the track (3) brings about a change in its
resistance, which is monitored by a constant current source (8) and voltmeter
(9). The degree of resistance change gives an indication of the energy content
of the microwave pulse.
On décrit un appareil qui sert à mesurer la puissance d'impulsions hyperfréquences intenses. L'appareil comprend une piste conductrice (3) formée sur un substrat isolant (1, 2) et couplée à un rayonnement émanant d'une source éloignée (10), par l'intermédiaire d'une antenne (7) et d'une ligne de transmission (6). Le chauffage subséquent de la piste (3) provoque une modification de sa résistance, laquelle est surveillée par une source de courant constant (8) et un voltmètre (9). Le degré de modification de la résistance donne une indication du contenu énergétique de l'impulsion hyperfréquences.
