Missiles like the Meteor and R-77M1 use ramjet propulsion, and the Amraam appears to use dual-pulse rocket propulsion.
The goals of both types of propulsion seem to be the same: improved endgame performance -- providing the missile with a burst of energy in the terminal stage to improve its ability to turn without losing energy.
But what is the main difference (from an operational perspective) between the two propulsion methods? As far as I can tell, ramjets have greater specific impulse, but lower acceleration. Dual-pulse rockets provide greater acceleration, but lower efficiency. What is the main difference between these two modes of propulsion, in terms of their operational use?
Just to clarify: this is NOT a "this vs. that" thread. I am NOT by any means trying to start a debate over which is the best missile, I'm just trying to learn more about them.
