I got a question is YIRAD now known as alp600 or something else because of the size difference. YIRAD was shown to be similar to tpy 2 and alp 600 is as big as 4 story building.
One interesting thing about YDYFR radar is that despite it being a "maritime surveillance radar" the Raytheon equalivent of it can detect and track but not target lock(because of low fidelity of the radar wave) F-35 sized aircraft from 80-120 km away and big passenger type aircraft from 280+ km away in daytime. Moreover generally is not effected by RAM painting and stealth geometry because of the huge wavelength of the radar waves(10-100 meters). I don't know if TÜBİTAK is working in this area for this project but can serve as a nice tripwire system against stealth platforms
TÜBİTAK’s 2025 activity report includes the completion of the YDYFR HF-band maritime surveillance over-the-horizon (OTH) radar project for the Turkish Navy.
