Capn kamikaze Posted August 10, 2019 Posted August 10, 2019 I just built a mission on the PG map where there's a Silkworm battery on the coast of an island, and according to the infobar the radar is at a height of 7ft, and I'd estimate the antenna's height about the same again. Let's say about 15ft total above sea level. There is a fairly accurate way to calculate the distance to the horizon, you take the height of be the observer above sea level in feet, multiply that by 1.5 and then take the square root of that, and that's a fairly accurate distance to the horizon in miles. So 15ft works out to about 4.75 miles. The Silkworm was attacking a small convoy of Elnya tankers, who were about 48 miles away. Let's say the bulk of the structure is 50ft high, it's horizon would work out to about 8.6 miles. So even with that added to the radars horizon means it is still quite a bit beyond the horizon. Yet they were visible.
S D Posted August 20, 2019 Posted August 20, 2019 Do you have an AWACS on the same coalition as the Silkworm? They can shoot over the horizon with an external sensor, pretty sure its only the AWACS atm.
Wizard1393 Posted August 21, 2019 Posted August 21, 2019 (edited) That's because Earth is flat in DCS! Yeah, true, but engagement / detection envelopes are capped programmatically to simulate IRL conditions. The Grim Reapers has done a YouTube video on this recently proving that this is the case.

Murey2 Posted August 31, 2019 Posted August 31, 2019 (edited) That's because Earth is flat in DCS! Not only in the game. Depending on wave band of the RADAR, the refraction of it change... that's what effect it even in real life not the claimed earth's curvature. Colors refractive index change due to the frequency and same thing with RADAR frequencies (bands) a good one with physics will understand it. Edited August 31, 2019 by Murey2
Capn kamikaze Posted February 2, 2020 Author Posted February 2, 2020 Refraction would be even less than the red in that, since radar is well below the wavelength of visible light, and I can't imagine that the quality of the signal after being refracted once out, and then again back would be good enough to detect something against sea clutter returns.
nighthawk2174 Posted February 3, 2020 Posted February 3, 2020 If you were to see over the horizon with a radar (that's not one of these massive units) you'd need an evaporation duct:
