Abstract:
1. A computer-implemented method for determining fratricide probability of projectile collision from a projectile launcher on a platform and an interception hazard ejectable from a deployment position, said method comprising: determining a firing zone of the platform, said firing zone presenting an area through which the projectile launcher operates; calculating an angular firing zone area from said firing zone that extends from the projectile launcher; quantifying a frontal area of the interception hazard to produce an intercept area with respect to the projectile launcher; translating said frontal area across a flight trajectory of said intercept area to produce a path area; and determining the fratricide probability for said deployment position from dividing said path area by said angular firing zone are, wherein the platform is a combat vessel, the projectile launcher is a gun, the interception hazard is a missile, and the deployment position is a vertical launch cell.
