Zusammenfassung:	The invention relates to an EIRP control method and device of a phased-array antenna. The control method comprises the following steps: calculating a reference EIRP of the phased-array antenna in real time according to a link budget of a low-orbit satellite and characteristics of the phased-array antenna; calculating link loss in a beam range of the phased-array antenna in real time; calculating the carrier-to-noise ratio of the EIRP transmitted by the phased-array antenna in real time; calculating off-axis EIRP attenuation of the phased-array antenna; and adjusting the EIRP value transmitted by the phased-array antenna in real time according to the received satellite signal strength. 本申请涉及一种相控阵天线的EIRP控制方法以及装置。该控制方法包括：根据低轨卫星的链路预算和相控阵天线的特性，实时计算出相控阵天线的基准EIRP；实时计算相控阵天线的波束范围内链路损耗；实时计算相控阵天线发射的EIRP载噪比；计算相控阵天线的离轴EIRP衰减；根据接收到的卫星信号强度，实时调整相控阵天线发射的EIRP值。
