Yes they do, but their FC radar can engage multiple targets. And if you are not happy with their current radar, I'm pretty sure the Israeli can upgrade the radar, for a price.
The Barak-1 system is more compact. How many MICA SAMs can fitted on a 1.5t corvette? while 24 barak-1 SAMs can be easily fitted on a ship less than 1ton. The only thing a barak-1 system has extra is the FC radar on top the ship, but that radar is not much bigger than the ones for the AK630.
Barak-1 can also handles multiple targets. Which one performs better I dont know. Perhaps the MICA is better but I'd rather have 24 SAMs than just 12, especially when you'll likely to be against more than 1 enemy ships with 8 AshM each.

Well, I like the Mica type of system better myself and you like the Barack 1 better, that's ok. The key point is that most of the Vietnamese naval ships don't have a proper air defense and any of these systems would be an improvement. I'll explain why I say this:
There are 3 modern ships in the Vietnamese Navy, Gepard, Sigma and Molniya.
The Sigma has the Mica, that's a good system, it can handle supersonic antiship missiles quite well. That will workout fine. The only think that I don't like is the cost of the missile at $3 million, way too expensive, but the system is good.
The Gepard relies on the Palma system and most people think that's good enough, but they are wrong. Why I say this?
A) The Palma Sosna-R missiles are laser guided and that means that in the presence of bad weather, fog, rain, etc, the laser beam can be interrupted. That's why the Russian Navy doesn't like it.
B) Here is the thing that most people don't know, it took me some digging up to find it. The Sosna-R can only intercept targets flying up to Mach 1.5 and that leaves a lot of chinese missiles out of the equation, that's bad news, very bad news.
C) This is more minor, but the Palma only has a range of 8 km.
The Molniya as already discussed is in bad shape for air defense having only the Igla system, which is just a MANPACK system.
The Molniya has an space issue in order to retrofit a better system, but the Gepard can do it. One of the options in the Gepard is to order it with the Shitil system, in which case it gets installed where the Palma system is now located. That would be the location to install a new system and the Palma can be moved to the back to replace one of the AK-630's. I hope VN will eventually do this.
