Abstract

Les fréquences de travail sont partagées entre quelques plages partielles de la gamme haute fréquence entière utilisée dans lesquelles, à des moments détrminés, on effectue de la transmission d'informations ou du radar éventuellement avec un changement de canal supplémentaire selon le procédé à sauts de fréquence. Aux moments où on ne fait pas de transmission d'informations ou de radar dans ces plages partielles utilisées, on effectue de l'EMC sous la forme de brouillage, sur le terrain des opérations au moyen d'une de plusieurs stations centrales à forte puissance d'émission.
