Title (EN) SYSTEM AND METHOD FOR SIMULTANEOUS DATA LINK WITH MULTIPURPOSE RADAR OPERATIONS
(FR) SYSTEME ET PROCEDE PERMETTANT LA MISE EN OEUVRE SIMULTANEE D'UNE LIAISON DE DONNEES ET D'OPERATIONS DE RADAR POLYVALENT
Abstract:
(EN) A technique for operating a communication link in RF proximity to an operational radar (60). A data link waveform is employed which allows a data link receiver (52) to detect an alert indication during normal radar operation. When the alert is detected, the system controller (70) briefly inhibits radar operation by issuing a transmit inhibit command (72) to receive the information content of the data link message. A data link message rate is selected to keep the impact to radar operation at a minimum.
(FR) L'invention concerne une technique permettant d'exploiter une liaison de communication à proximité HF d'un radar (60) opérationnel. On emploie une forme d'onde de liaison de données qui permet à un récepteur (52) de liaisons de données de détecter une indication d'alerte au cours du fonctionnement normal du radar. Lorsque l'alerte est détectée, l'organe de commande (70) du système inhibe brièvement le fonctionnement du radar en produisant une commande (72) d'inhibition d'émission pour permettre la réception du contenu d'informations du message de liaison de données. Un débit de message de liaisons de données est sélectionné pour maintenir l'impact sur le fonctionnement du radar à un minimum.
