sarkit.sicd.projection.compute_projection_sets

compute_projection_sets(proj_metadata, image_grid_locations)

Compute Center of Aperture projection sets at specified image grid locations.

For a selected image grid location, the COA projection set contains the parameters needed for computing precise image-to-scene projection. The parameters contained in the COA projection set are dependent upon the proj_metadata.Collect_Type.

MONOSTATIC

t_COA, ARP_COA, VARP_COA, R_COA, Rdot_COA

BISTATIC

t_COA, tx_COA, tr_COA, Xmt_COA, VXmt_COA, Rcv_COA, VRcv_COA, R_Avg_COA, Rdot_Avg_COA

Parameters:
proj_metadataMetadataParams

Metadata parameters relevant to projection.

image_grid_locations(…, 2) array_like

N-D array of image coordinates with xrow/ycol in meters in the last dimension.

Returns:
ProjectionSetsLike

Ensemble of Center of Aperture projection sets.
