A DIGITAL SIMULATION PROGRAM FOR THE INTERCEPTION OF A TARGET BY AN INTERCEPTOR USING PROPORTIOAL NAVIGATION SCHEMES,
Abstract
This report is a handbook for the use of the TGIF program which has recently been modified. The TGIF program is a digital simulation program which may be used to study the boost, midcourse, and homing phase of the interception of a target by an interceptor using propo1tional navigation. The program will be most useful after hand calculations have established general tactical cases, and before complex guidance and control studies are performed on an analog computer. Given the initial positions, velocities and accelerations of the target and the interceptor, the target acceleration profile, and guidance parameters for the interceptor guidance system, this program computes a homing intercept trajectory based upon maintaining a zeroline-ofsight rate between the target and itself. The equations of motion are written in a relative coordinate system fixed on the target position. Gravity effects are not included; however, accelerating targets may be considered. The option of biased proportional navigation is also available. Homing thrust orientation is obtained by either of two methods: Roll-to-turn and Y configuration (3 engines) with a roll capability.
