It seems to me that RCS measurements using software and 3D models have recently become the sole measure of stealth.
For example, such analysis suggests that the F-35 has extreme stealth characteristics, such as -40db.
In reality, however, the RCS is far from the theoretical value.
For example, Karrar should have almost the same RCS as Tomahawk, which is rumored to have an RCS of -10 to -20db, due to its shape and size,
However, the actual RCS of Karrar was found to be 2.1db, based on the video footage of the Bavar-373 exercise.
A Japanese government study of various drones, such as the DIJ, found their RCS to be -10db to -20db.
The -20db value was measured for a very small micro drone.
Micro-drones are generally considered to be more difficult targets to detect than stealth fighters.
For reference, the micro drone (E) in the photo above has a measured value of -19.1db in the KU band.
The measured value of the
bionic bird in (F) is -23db to -25db.
This value should be slightly lower than that of the X band, but it should serve as a reference.
I would like to ask you, do you think it is possible for a stealth fighter to have a shorter detection range than (F) man-made birds?
Maybe the (F) artificial bird is almost undetectable even in Israel?
In fact, the U.S., South Korea, Israel, and other countries often allow micro drones to penetrate their territory.
We believe that the social networking discussion is being driven by U.S. propaganda, and that the figures are overstated, which is highly unlikely.
For example,
Japanese airport safety standards for radar that can detect a foreign object of a few centimeters rolling on the runway without clutter noise are
The radar must be capable of detecting objects of
-20db.
Which is a more difficult target, a few centimeter object rolling on the runway (i.e., Doppler shift is 0!) or a micro drone?
Naturally, it is a foreign object of a few centimeters on the runway. Of course it is a more difficult target than a stealth fighter!
I hope you know that the numbers on social networking sites and reality are far apart.
The above Japanese safety standards are not fantasy, but legal reality.
