A novel integration approach is developed for efficiently evaluating double surface integrals in time-domain integral equation formulations. The approach mainly consists of an angular integration scheme for inner 2-D integrals and a modified outer integration scheme. The approach proposed can handle the singularity and near-hypersingularity of the 4-D integrals, and is sufficiently general for arbitrary...
The adaptive phase-only beamforming technique is very important for conventional phased array radar to suppress interference. Similar to conventional phased array radar, for the digital array radar, the adaptive phase-only beamforming technique is also very useful and can be used to enhance the radar power by making full use of transmit module microwave power of each array element. In this paper,...
A novel scheme that uses quadratic B-spline temporal basis function(TBF) and accurate evaluation of the MOT matrix elements is proposed. For solving time domain integral equation (TDIE) equation of transient scattering problems, this TBF permits consistent approximations of the induced currents and charges, leading to proper representations of the fields contributed by both the vector and scalar potentials...
