Answer» CORRECT option is (B) Low RCS Explanation: Military aircraft usually wish to have a very low RCS or radar cross section so that they are stealthy and undetectable on the enemy’s primary radar. RCS can be REDUCED by various methods like using radar energy absorbing MATERIALS on the surface of the aircraft and not having sharp corners on the aircraft which are more likely to reflect radio energy back to the radar ANTENNA. |
