Abstract
The implementation of Sense And Avoid (SAA) capabilities on Unmanned Aircraft Systems (UAS) present a particular challenge in that collision threats can be either cooperative or non-cooperative. Cooperative aircraft are here defined as being equipped with ADS-B that broadcasts that aircraft"s position and velocity vectors. Non-Cooperative targets must be addressed with radar sensors that detect, acquire, track, and determine the targets collision potential as well as support the clearing maneuvers. ADS-B signals lack encryption and can be readily spoofed for drug trafficking, identity denial and false target generation purposes. Spoofing can translate the position of drug traffickers away from drop zones. Enemies may want to hide the identities of military aircraft as commercial traffic or flood the skies with false targets to stress or overwhelm the system to hide ulterior activities. This investigation is focused on merging ADS-B and RDRTec"s Fire Scout SAA radar in a manner that increases the total SAA system performance against cooperative and non-cooperative which includes added immunity of ADS-B spoofing.
