    • Antennas used aboard aircraft to communicate with satellites or ground stations may have complex antenna patterns, which may vary as the aircraft moves throughout a given coverage area. Techniques are disclosed for dynamically adjusting the instantaneous power fed to an antenna system to ensure that the antenna transmits at the regulatory or coordinated effective isotropic radiated power (EIRP) spectral limit. The antenna may transmit, in accordance with aircraft location and attitude, steerable beam patterns at different scan and skew angle combinations, causing variations in antenna gain and fluctuations in the transmitted EIRP. Using on-board navigational data, an antenna gain and ESD limit may be calculated for a particular scan and skew angle, which may be used to adjust power fed to the antenna such that the antenna transmits substantially at maximum allowable EIRP as the steerable beam pattern is adjusted.
    • 在飞机上用于与卫星或地面站通信的天线可能具有复杂的天线方向图,当飞机在给定的覆盖区域内移动时,天线方向图可能会有所不同。 公开了用于动态调整馈送到天线系统的瞬时功率以确保天线以调节或协调的有效各向同性辐射功率(EIRP)频谱限制发射的技术。 根据飞机位置和姿态,天线可以在不同的扫描和倾斜角度组合处传输可控波束方向图,引起天线增益的变化和传输的EIRP的波动。 使用机载导航数据,可以针对特定的扫描和倾斜角来计算天线增益和ESD极限,其可以用于调整馈送给天线的功率,使得天线基本上以最大可允许的EIRP传输作为可控波束图案 被调整。
