A project I made a while back about proportional navigation guidance in missiles. I shared it because why not. Use WASD to control the target drone. Proportional navigation is based on a very simple principle: if you are moving towards a target on an intercept course (assuming your speed and the target's speed are constant), the angle to the target doesn't change as you approach it. This means that, without even knowing the target's distance and speed, you can rely on the bearing to the target alone to intercept it. What if the angle to the target changes? In this case, you turn by an angle greater than the delta angle (the angle-to-the-target's variaton), usually by multiplying it by a constant greater than 1 and then turning by that amount. This means that the missile DOESN'T need to know where it is, although for better intercept courses and other advantages modern missiles do.
