Path planning is an effective means to improve the operational effectiveness of aircrafts. A reasonable estimation and description of threats existing in operation space are significant before generating a specific path for an aircraft. To avoid depending on experts' experience excessively when we evaluate the threat situations, an index based threat modeling method named IBTMM is proposed. IBTMM...
In this paper, a local multilevel fast multipole algorithm (LMLFMA) based on an improved electric field integral equation (IEFIE) is developed to achieve fast and efficient solution of electromagnetic scattering from 3-D conducting structures. The IEFIE is used to reduce iteration number, and LMLFMA is applied to further accelerate the computation of matrix-vector multiplications in iteration, in...
