《华盛顿邮报》周六援引泄露的美国情报文件报道称，今年 2 月被美国击落的中国间谍气球携带有太阳能电池板，它可以为一种可以在夜间和云层中生成图像的雷达提供足够的电力。
《华盛顿邮报》称，美国国家地理空间情报局（NGA）的一份文件详细地描述了这只气球的监视能力，该文件据称是由马萨诸塞州空军国民警卫队成员 Jack Teixeira 泄露到 Discord 聊天室的。
21 岁的 Jack Teixeira 周五在波士顿被指控非法复制和传播机密材料。
《华盛顿邮报》称，根据 NGA 的文件，这只气球可以产生高达 1 万瓦的太阳能，足以运行一个被称为合成孔径雷达（synthetic aperture radar）的复杂监视系统。
报道称，这种雷达可以在夜间传回图像，并能穿透云层和防水布等质地薄的材料，显示下面的目标物。
《华盛顿邮报》说，该气球携带有一个直径 1.2 米的抛物面天线，几个用途不明的传感器和一个或许是桅杆式的天线。
五角大楼拒绝了路透社寻求评论的请求。
