And if the range spec is true then I am disappointed , a fixed 4 planer array with range of 450km @ 2m2 rcs that's low.
Drdo specifically mentioned 900 km range for HPA, now am wondering at what RCS .
This is a good enough range. I just finished checking the ranges of contemporary long range air surveillance radars
EL/M-2288 AD-STAR has a 480 km intrustumented range. The MR variant can detect a typical fighter sized target at 300+km and the ER can detect at 430+ km.
Ground Master 400 series radar from Thales Raytheon also has a 470 km instrumented range against air breathing targets.
The FPS-117 family from Lm has a 470 km instrumented range. And it has a 330 km detection range for a 1sqm target.
The AN/TPS-77 which forms the bedstone of PAF air defense and surveillance network has a 470 km instrumted range. Against 1sqm targets it has a 300 km detection range.
Our of these four only the AD-STAR and GM-400 has a TBM detection and track capability. There's also a GM406 variant with a 15 percent higher track range.
The EL/M-2083 has a 250 km detection range against fighter sized targets. Although it doesn't belong in the same group, I am mentioning it to give you people a comparison of radar ranges.
Compared to the above Long range air space surveillance radars, the Drdo HPR has a superior detection and tracking range. It is also superior to all the above systems in its unique architecture and configuration. A land based variant of MF-Star.
This HPR will also be having ballistic missile detection and tracking capabilities. So it can play a secondary ABM early warning and track role.
What's left to be known is the radar operating band. If it's a L band it will be awesome since L band also has an inherent advantage against VLO targets and is less affected by precipitation.
