摘要： Le systeme fournit a chaque avion donne equipe (10) une indication de la presence d'un avion genant equipe de la meme maniere. Differentes zones sont etablies autour des avions donne et genant et l'indication fournie permet a chaque pilote de savoir lorsque deux de ces zones se chevauchent. Les zones sont etablies en positionnant une pluralite d'antennes de transmission/reception (12, 14, 16, 18, 20, 22) autour du corps de chaque avion. L'angle de dispersion et la portee de chaque antenne definissent une zone separee. Chaque antenne transmet un signal code pour indiquer la situation de sa zone sur son avion respectif, et elle est equipee pour recevoir des signaux codes de la meme maniere transmis par l'autre avion. Ces signaux sont decodes pour donner indication de la zone de l'avion genant de la zone definie par l'antenne de reception de l'avion donne. Cette information est affichee sur un tableau d'affichage (45) monte dans le cockpit pour produire un signal d'avertissement d'une collision imminente, lequel montre egalement les positions relatives des deux avions. Des emetteurs peuvent egalement etre montes sur des sommets de montagnes ou autres obstacles pour indiquer leur presence a tout avion se trouvant a proximite dangereuse de ceux-ci.

摘要： Examples are disclosed that relate to adaptively adjusting a radio frequency (RF) signal to suppress interference with radio operation of a prioritized RF system while maintaining radio operation of a non-prioritized RF system. In one example, a system (200) includes an antenna array (202), a RF signal detection subsystem (204), and a signal-forming subsystem (206). The RF signal detection subsystem (204) is configured to detect a prioritized RF signal (212) in a prioritized RF spectrum band and determine an angle of arrival (214) of the prioritized RF signal (212). The signal-forming subsystem (206) is configured to output a non-prioritized RF signal (210) based at least on the angle of arrival (214). A radiation null (226) is formed along the angle of arrival (214) in a radiation pattern (224) of the non-prioritized RF signal (210). The signal-forming subsystem (206) is configured to transmit the non-prioritized RF signal (210) via the antenna array (202).
