Some projects of Tübitak SAGE are shelved. As far as I know, G40 is one of them.
Hisar-O RF seeker improvements are related to the naval environment. The major improvement is against RF sea clutter when intercepting super sea-skimming missiles.
IIR improvement might be related to the HOT T2SL and MCT detectors. I have been hearing big breakthroughs from Aselsan in the HOT IIR photodetectors area. HOT detectors provide the same performance but require less cryogenic cooling. Less cryogenic cooling means less power consumption, smaller cooling solution, etc. That means SWaP-C gains.
Radar is Kalkan-II
It has multiple beam forming, pulse compression, pulse coding, Advanced ECCM etc. good stuff.
