As to the problem of grating lobes suppression for wide-band reconnaissance DBF, a new method is proposed based on the technology of virtual antenna. The array antenna in the method uses main array antenna plus auxiliary array way. DBF algorithms in the method don't need to know the prior knowledge of reconnaissance signal and don't need complex matrix inverse operation, instead of it, the two kinds...
For solving Bessel function's singular problem of Sommerfeld integral in calculating the spatial domain Green's function of cylindrically stratified media, a domain-division algorithm is proposed in this paper, which can realize the computation for all elements of Z-matrix in the method of moment. Then, arbitrary shape cylindrical conformal microstrip antenna (CCMA) fed by microstripline is theoretically...
A coupled surface-volume integral equation approach is presented for analysis of arbitrarily shaped microstrip antennas on finite ground substrate. The method is more universal than traditional MoM. The basis functions defined in pairs of tetrahedral volume elements (SWG) and on pairs of triangular patches (RWG) are used to represent the unknown currents in dielectric cells and on conductive patches...
