3-D Radome-Enclosed Aperture Antenna Analyses and Far-Side Radiation

Electromagnetic wave scattering by aerial and ground radar objects

“…[80,81]. The ray passing through such caustic surface changes its phase by π/2 [82,83], which has to be taken into account for the wave hitting the antenna after reflection from the radome inner surface.…”

Fast Analysis of Electrically Large Radome in Millimeter Wave Band With Fast Multipole Acceleration

“…In the antenna-radome model, an aperture antenna in an ideally black screen is enclosed by the dielectric radome [5,13]. When the equivalent electromagnetic currents on the aperture of the antenna are known, the first incident fields on the inner surface of the radome can be obtained by integrating the currents over the antenna aperture using the following formulas:…”

“…R ⊥ , R // , T ⊥ , T // are the reflection and transmission coefficients for the perpendicular and parallel polarization components [7,20]. The reflected fields on the inner surface may bounce in the radome and they have important effects on the flash lobe of the antenna-radome system [12][13][14]. In order to account the mutual interactions between different parts of the radome, the fields radiated from the reflected fields must be calculated.…”

“…Some portion of the first incident fields will transmit through the radome wall and the remaining will be reflected by the wall. The reflected fields have important effects on the flash lobe of the radiation pattern [12][13][14]. By integrating the reflected fields over the inner surface of the radome, the second incident fields on the inner surface of the radome can be obtained.…”
