2 weeks ago Don't think it could detect target at 1500nm. This is what a 1500nm strategic OTH-B Radar looks like:
The SIAR seems to be only 1/3 of the above one's size:
Personally speaking, 500nm would be reasonable. What does our dear DB manger think?

Comments
According to satellite images released as early as 2016, the PLA has installed SIAR at its bases in the South China Sea to monitor the air posture of neighboring countries. The analysis believes that the radar works in the 100mhz-200mhz band, the purpose is to effectively monitor the stealth fighters of various countries. In response to the United States' powerful stealth technology, China's use of this unique new radar as a counter measure is worth keeping track of.
