sarkit.crsd.compute_h_v_los_unit_vectors

compute_h_v_los_unit_vectors(apc, gpt)

Compute H, V, LOS unit vectors as in CRSD D&I 9.4.3

Parameters:

apc(…, 3) array_like

Antenna phase center position with ECEF X, Y, Z components (m) in last dimension.

gpt(…, 3) array_like

Scene point position with ECEF X, Y, Z components (m) in last dimension.

Returns:

uhor(…, 3) ndarray

Unit vector that points in the +H (horizontal) direction with ECEF X, Y, Z components (m) in last dimension.

uvert(…, 3) ndarray

Unit vector that points in the +V (vertical) direction with ECEF X, Y, Z components (m) in last dimension.

ulos(…, 3) ndarray

Unit vector that points from apc to gpt with ECEF X, Y, Z components (m) in last dimension.
