您说的是广播式自动相关监视ADS-B么？如果是，那么ADS-B有三种制式：1090，UAT，VDL M4。1090的调制方式是PPM；UAT的调制方式是binary Continuous Phase Frequency Shift Keying；VDL M4已经几乎没人用了，不知道是不是2ASK。最常用的是1090，调制方式是PPM，不是2ASK。

the information for an aircraft equipped with a 1090MHz ADS-B Out system will be re-broadcasted to an aircraft equipped with ADS-B In on the UAT (i.e. 978MHz) frequency, and vice versa.
The use of Unmanned Arial Systems (UAS) inboth civil and military applications has greatly increasedover the last few years. At the same time, issues relatedto the safety of air traffic operation arise when consideringUAS insertion into non-segregated airspace. Thus, surveillanceplays a key role...
