re: PLAN Type 052 Class Destroyer
Well just look at the missile trails, you can easily tell that its two pairs of missiles since they have similar trajectories to each other, but they are distinctly different from the other pair.
The pair with the more gentle curve are the AShMs, since they do not want to go very high at first as that wastes fuel and increases the chances of detection.
The pair with the steeper climb angle and sharper dip afterwards are the SAMs, since their typical launch profile is to climb rapidly to engage high flying aircraft, but in this case, they dived down soon after, probably to engage sea skimming air targets. Such climb-stoop profiles are quite common amongst SAMs, especially naval SAMs. There are plenty of vids online showing SM1/2 missiles with a very similar flight path.
