The L-Band radar array of LRTR can track a 0.1m2 target at 1500kms away and using this formula: 1500x(0.0001÷0.1)^(1/4) gives a range of 267 kms for tracking of a 0.0001m2 or -40dBsm target. And our radar tech is evolving each year. Rather than in next two decades, we'll be able to track VLO & ELO targets from well beyond 400kms maybe within next two years,)

Its maximum range is upto *1500km*
upgraded version of India's indigenous Swordfish Long Range Tracking Radar (LRTR), designed to track ballistic missiles up to 1,500 km.
A reentry warhead of a MRBM's generally has MEDIAN rcs of 0.1-1m2 range
Not 0.1m2 as a SINGLE number.
A MRBM( re-entry + booster) generally has median RCS of 3-10m2.
The still UNCOMFIRMED but most known stat about its performance is( not Google instant search ones)
" able to detect objects as small as a cricket ball at long distances"
"with the quantitative RCS figure of 0.25 m² at 1,000 km"
If we assume this figure as accurate.
The radar will detect a 0.1m2 target at a range of ~800km.
and a 0.0001m2 target at a range of ~140km.

Also radar horizon/line of sight of a ground radar for a fighter/object flying at
20,000 feet is ~320km.
30,000feet is ~400km
40,000 feet is ~450km.
Which is not *well beyond* 400km.
For fighter jets, Cruising for fuel efficiency usually occurs at 31,000–42,000 feet.
