Stealth technology has added an inspiration in the ¯eld of electronic counter mea- sure and has brought out the ine®ectuality of the mono-static radars. The stealth aircrafts scatter very low intensity electromagnetic radiations due to its special geometry and absorbent material. However, if an electromagnetic wave is incident at `good' angles, stealth aircraft though low ob- servable cannot be called as invisible. In this paper, the results of the extensive simulations on a model stealth aircraft have been presented. Simulations are performed, on an aircraft model to prove the e®ectiveness of the proposed model. By energizing the aircraft at `good' angle(s) of incidence, signi¯cant scattering can be observed over a range of aspect angles. Thereafter, a multi-static approach is proposed making a polygon arrangement of radar transceivers in order to guarantee the detection of a stealth aircraft.
