ProNav - Proportional Navigation Missile Guidance

Demostration for accurate 2D missle guidance with simulated aerodynamics.

Features:

• 4 separate guidance solutions.
• Multiple target types. (Static, Linear, Rotating, Erratic)
• 2D aerodynamics (Lift, Drag, Torque)
• 2 control modes (Direct rotation or movable control surfaces)
• High performance Direct2D rendering.
• Radar guided auto-cannon. (ProNav style target leading)
• High speed collision detection.

Remarks:

This actually started as an Asteroids clone but then I went down a rabbit hole of missle guidance, so I started a new project...

I felt that nearly all examples I found were cheating by directly setting the instant velocity of the missile. Instead, I sought to implement realistic physics with aerodynamics, mass and inertia and to create a guidance solution which only effects the rotation (either by direct manipulation or indirectly via control surfaces/wings).

I included 3 simple PN guidance solutions based on other examples, and one "Advanced" solution of my own making. My solution tries to perform better long-term predictions as well as handle cases in which the missile "rat chases" the target in endless circles. A handful of target types are available to test them against.
