Bro to much success and its very lonely at the top as nobody noticed you and you're being ignored....lol
I just saw this and frankly I'm very surprised. Esp radar, why can't they leverage their semiconductor industries?
Because radar doesn't use silicon for the transceiver elements, they use compound semiconductor III-Vs like GaN, GaAs, etc due to their much higher carrier mobility which enables them to carry high frequency signals without overheating or high loss.
The compound semiconductor industry involves different wafer sizes, processes, chemicals, etc than silicon. Wafer fabrication itself is much more difficult than silicon.
I think a lot of it is legacy baggage. South Korea is one of the major makers of cellphone towers and cellphone equipment. So they certainly have the technology base to make radar if they wanted to. KM-SAM is an S-350 SAM clone which uses South Korean electronics.
Naomi Wu did once explain that stopping forgeries was as easy as hiring an IP lawyer in China to do the due delligency, but it was cheaper to whine about it
Seems Korea kinda "neglect" research&development in material science, explain weakness in marine turbine too.
