Collect multiple post-processed products from one stored TMM solve
Source:R/tmm-bistatic.R
tmm_products.RdProvides a higher-level convenience interface for the stored-block TMM workflow. One call can return the monostatic scattering spectrum, an orientation average, and a higher-level bistatic summary without rebuilding the underlying T-matrix solve. For stored cylinders, the currently supported products are the exact monostatic scattering spectrum and the corresponding orientation-averaged monostatic outputs; cylinder bistatic summaries remain unavailable until a validated retained cylinder angular operator is added.

)Arguments
- object
Scatterer-object previously evaluated with
target_strength(..., model = "TMM", store_t_matrix = TRUE).- frequency
Stored frequency (Hz) used when
bistatic_summary = TRUE.- theta_body
Incident polar angle (radians) for the monostatic and bistatic products. Defaults to the stored TMM incident angle.
- phi_body
Incident azimuth angle (radians) for the monostatic and bistatic products. Defaults to the stored TMM incident angle.
- orientation
Optional orientation distribution created by
tmm_orientation_distribution.- bistatic_summary
Logical; include the output of
tmm_bistatic_summary.- include_grid
Logical; keep the 2D scattering grid inside the bistatic summary output.
- n_theta
Number of receive polar-angle samples for the bistatic summary.
- n_phi
Number of receive azimuth samples for the bistatic summary.
- n_psi
Number of forward-centered angular samples used by the local summary slices.
- sectors
Optional angular-sector table passed to
tmm_bistatic_summary.- drop_dB
Positive dB drop used to define the backscatter-lobe width.
