| Abstract: |
| A method of an automatic air collision avoidance system(ACAS) based on data
link is presented in this paper. According to the basic requirements on the Aut
o-ACAS, the working principle and flow of the system are analyzed. The mathemat
ical model of optimal escape is given by curve fitting both the flight path of tw
o Unmanned Aerial Vehicles(UAVs) with quadratic curves as a function of time, a
nd by
finding the analytic solution to the minimum separation distance between two cu
rves. The simulation results indicate that the Auto-ACAS can provide mid-air a
pproaching collision protection for UAVs at the last moment. |
