Abstract

L'invention concerne un dispositif perfectionné d'asservissement en phase de l'oscillateur cohérent d'un radar Doppler à impulsions. Selon l'invention, le signal à fréquence intermédiaire dérivé du signal émis par le radar est appliqué à un circuit d'ébasage 20 qui élimine les signaux parasites dont l'amplitude est faible. Le signal de sortie du circuit d'ébasage 20 est, après amplification (circuit 21) et filtrage (circuit 22), utilisé pour commander en phase l'oscillateur cohérent du radar. L'invention s'applique aux radars Doppler à impulsions utilisant un magnétron auto-oscillateur.
