Numerically simulating survivability of high-altitude unmanned reconnaissance aerial vehicle (URAV)

Section 1 of the full paper, after analyzing in some detail the relationships among the susceptibility, vulnerability and survivability of the high-altitude URAV, establishes its survivability model. Section 2 explains in some detail how to implement the numerical simulation of the survivability model and then explains the factors of influence, including the shortcut flight course, flight altitude, flight velocity and radar cross section (RCS) of the URAV. The block diagram, as shown in Fig.1, gives the simulation flow chart of survivability. Section 3 presents two numerical examples. The numerical results, given in Figs.2 through 5, and their analysis show preliminarily that the survivability probability of the URAV increases with increasing shortcut flight course, increasing flight altitude, increasing flight velocity and decreasing RCS. The numerical results, given in Figs.6 through 9, show preliminarily that, with the same survivability probability, the above-mentioned survivability-increasing measures can increase the penetration distance of the URAV.
