Abstract

Dans un dispositif à radar Doppler pour la surveillance locale, l'oscillateur constitue en même temps le détecteur. Il contient un transistor à effet de champ, muni dans son circuit de source et de drain d'un élément de circuit pour le prélèvement des signaux de fréquence Doppler, connecté par l'intermédiaire d'un filtre. On obtient ainsi un dispositif particulièrement simple et de fabrication avantageuse, peu volumineux, léger et d'une fiabilité élevée.
