Asymptotic Solver Angle SweepSimulation: Solver Start Simulation Excitation angle sweeps / Observation angle sweeps (Add / Edit)This dialog box allows you to add or edit a particular angular sweep definition for excitation angle sweeps or observation angle sweeps.
For excitation angle sweeps, the solver will calculate the results for all angular directions defined by individual sweep definitions. You may either just add one excitation angle sweep definition for uniform sampling or you may add multiple excitation angle sweeps in order to achieve a non-uniform angular sampling. Please note that the number of excitation angles has a linear influence on the solver runtime.
For observation angle sweeps, the solver will calculate the scattered field results separately for each sweep definition. Depending on the type of the sweep, the results can then either be visualized as one dimensional curves or optionally as two dimensional farfield plots. Typically, a relatively coarse two dimensional sweep is defined in combination with one or more refined one dimensional sweeps. Please note that the number of observation angles has a linear influence on the solver runtime.
Type Specify the type of the angular sweep definition. You can choose one of the following options:
Store rays for each excitation direction This option is available for excitation angle sweeps or observation angle sweeps in monostatic or range profile mode. The setting specifies whether the rays will be stored for each angular direction defined by the angular sweep. Theta min / Phi min Specify the lower angular bound for the sweep definition. The availability of these entry fields depends on the Type definition. Theta max / Phi max Specify the upper angular bound for the sweep definition. The availability of these entry fields depends on the Type definition. Theta step / Phi step Specify the angular step width for the sweep definition. The step width must match with the specification of the lower and upper angular bounds. The availability of these entry fields depends on the Type definition. Theta / Phi Specify the fixed angle in case of a one dimensional sweep definition or a single point specification. The availability of these entry fields depends on the Type definition. OK Accepts the changes and closes the dialog. Cancel Closes this dialog box without performing any further action. Help Shows this help text.
