“…The points (x p , y p ) and (x e , y e ) are current coordinates of the pursuer and the evader, respectively, a p , a e are their lateral accelerations, ϕ p , ϕ e are the respective angles between the velocity vectors and the x-axis (initial line of sight). Based on the small angles assumption (Shinar, 1981;Shima and Shinar, 2002;Shinar et al, 2013), the trajectories of the pursuer and the evader can be linearized with respect to the nominal collision geometry, leading to a constant closing velocity V c . The final interception time t f can be easily calculated for any given initial range r 0 : t f = r 0 /V c .…”
