Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. [1] An object reflects a limited amount of radar energy back to the source. The factors that influence this include: [1] the material with which the target is made;
Stealth aircraft are still vulnerable to detection while and immediately after using their weaponry. Since stealth payload (reduced RCS bombs and cruise missiles) is not yet generally available, and ordnance mount points create a significant radar return, stealth aircraft carry all armaments internally. As soon as weapons bay doors are opened ...
The term stealth in reference to reduced radar signature aircraft became popular during the late eighties when the Lockheed Martin F-117 stealth fighter became widely known. The first large scale (and public) use of the F-117 was during the Gulf War in 1991.

While the exact extent of the 360s stealth properties may not be available for security reasons, the visible external shape and internal weapons bay do seem to exhibit radar signature reducing capabilities. [32] During October 2018, leaked images of a future as-of-yet unnamed Kamov helicopter that possessed stealth features appeared online. [33]
The radar began to be investigated in 1984. The radar complex is made up of a command post module and one to three different radars which are deployed on separate 8x8 24-ton trucks. The manufacturer claims this radar system can detect 5th generation aircraft like the F-22 and F-35 [3] and detect long-range ballistic missile launches. Nebo-ME is ...

Many of the specifics of the aircraft and the overall programme have remained concealed. While detailed information in regards to the Lampyridae's radar signature and its testing are considered to be classified information, however, it is known that the targets for the airframe's radar cross-section were considered to have been achieved.
