Most direction-of-arrival (DOA) estimation approaches for conformal array suffer from high computational complexity, which cause high energy loss for the direction finding system. Thus, a low energy consumption DOA estimation algorithm for conformal array antenna is proposed in this paper. The arbitrary baseline direction finding algorithm is extended to estimate DOA for a conformal array in ultra-wideband. The rotation comparison method is adopted to solve the ambiguity of direction finding. The virtual baseline approach is used to construct the virtual elements. Theoretically, the virtual elements can be extended in the space flexibility. Four elements (both actual and virtual elements) can be used to obtain a group of solutions. The space angle estimation can be obtained by using sub-array divided technique and matrix inversion method. The stability of the proposed algorithm can be guaranteed by averaging the angles obtained by different sub-arrays. Finally, the simulation results verify the effectiveness of the proposed method with high DOA estimation accuracy and relatively low computational complexity.

“…The ultra-wideband direction finding for conformal array antenna is still an extremely severe problem at present. The interferometer [25][26][27] direction-finding method is another kind of DOA estimation method which can be used for ultra-wideband direction finding [28][29][30][31]. The algorithm in [28] does not need a grid search.…”

“…However, the limitation associated with the ES mainly lies in its inadequacy in differentiating, uniquely, each individual deterioration mechanism, such as carbonation, as the electrical properties of concrete can also be affected by other factors such as moisture change, ions ingress and ongoing hydration. Due to this reason, fibre optic sensors (FOS) have attracted tremendous attentions in recent years for its merits of inert nature, immunity to electromagnetic interference, lightweight/miniature and multiplexing into multisensing [34][35][36]. More importantly, FOS can overcome the drawback of ES by encapsulating the fibre tip with specific chemical dyes so that each individual deterioration mechanism can be uniquely differentiated [30 ,36-38].…”

Abstract-A frequency dependent model of sheet resistance of transparent conductive mesh coatings is proposed based on transmission line theory and vilified by experiments. And the effect on shielding effectiveness of frequency dependent sheet resistance is analyzed. Simulation results of shielding effectiveness are compared with the experimental data of a mesh-coated window sample with equivalent parameters fabricated and measured by Exotic Electro-Optics. The agreement between experiment and simulated proves the validity of the proposed sheet resistance model. So it can be therefore concluded that the frequency dependent model can be used to reasonably evaluate sheet resistance and shielding effectiveness of transparent conductive mesh coated windows.
