使用ADS - B技术速度变化传播信号作为状态向量报告一部分，几乎是一瞬间就能探测到。
With ADS-B, velocity changes are broadcast almost instantaneously as part of the State Vector report.
特征提取的依据是利用有关数学工具，去掉对分类无用的信息，寻找最有效的信号特征来构成用于分类识别的模式特征向量。
The extracting process is to throw off the useless information and look for the most efficient signal feature to form a pattern feature vectors for classification with mathematics tools.
该文只考虑了接收天线选择，天线选择的准则是基于每个天线接收到的信号向量F-2范数。
Selection criterion is based on the Frobenius-2 norm of received signal vector at each receiving antenna.
