sarkit.sicd.projection.ProjectionSetsMono

class ProjectionSetsMono(*, t_COA, ARP_COA, VARP_COA, R_COA, Rdot_COA)

Ensemble of monostatic Center of Aperture projection sets.

For a selected image grid location, the COA projection set contains the parameters needed for computing precise image-to-scene projection.

Constructor arguments are array_like and broadcast into the attributes after an implicit, right-most dimension is added to t_COA, R_COA and Rdot_COA. The implicit dimension is subsequently removed

Attributes:
t_COA(…) ndarray

Center of aperture times in seconds relative to collect start

ARP_COA(…, 3) ndarray

Aperture reference point positions with ECEF X, Y, Z components (m) in last dimension

VARP_COA(…, 3) ndarray

Aperture reference point velocities with ECEF X, Y, Z components (m/s) in last dimension

R_COA, Rdot_COA(…) ndarray

Ranges (m) and range rates (m/s) relative to the ARP COA positions and velocities
