Realistic Missile Modeling for Guidance Applications

In this paper, a general missile modeling is presented. An accurate model for missiles is proposed taking into consideration the rigid body dynamics in 3D space with 6 degrees of freedom. Different coordinate systems, variation of missile mass, aerodynamics, air speed and density, gravity, propulsion system, actuators, measurement and tracking devices are also considered. The full model is implemented and integrated within a simulation environment to facilitate missile guidance design. The developed model is optimized for both high simulation speed and accurate calculations. Other modules are implemented to calculate aerodynamics coefficients, generate random signal, provide both conventional and intelligent control, and represents the missile-target engagement visually. The whole system is successfully used to implement different guidance techniques
