Book for missile simulation

Hi.

For a project that I'm working in, I need to implement a missile simulator.

I've found a plenty of books about dynamics of real missiles, like Missile Aerodynamics by Nielsen.

These books are good, but they're too related to real missiles, while I need something more specific for simulations, where I don't need to calculate exactly the aerodynamics and actuator controls, but I need only that they have a realistic behaviour.

Do you have some book/article/bibliography to suggest focused on missile simulation?

A lot of soviet era SAM systems got unclassified long time ago and there is their documents available for them, from their guidance systems to operations etc. You could search for those.

I've found something related to them, but nothing specific to simulation unfortunately..
