Electromagnetic Design of Stealth Unmanned Combat Aerial Vehicle in Hostile Environment

Low observable techniques for stealth applications have become the need of the hour. RCS analysis for airborne platforms in military bands is the stringent requirement. Techniques such as shaping of aircrafts and use of absorbers suppresses radar echoes. This paper discusses about the use of special absorber techniques such as multi-layered Radar Absorbing Techniques with and without FSS to cater the reduction of echoes in the X-Band. The RCS analysis with and without absorber for Unmanned Combat Aerial Vehicle has been compared and analysed. The target tracking for the UCAV has also been covered in hostile environment condition using Altair Feko.
