compute_h_v_pol_parameters(apc, uacx, uacy, gpt, xr, ampx, ampy, phasex, phasey)

Compute H, V polarization parameters as in CRSD D&I 9.4.4

Parameters:

apc(3,) array_like

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

uacx, uacy(3,) array_like

Antenna coordinate frame unit vectors in the +ACX and +ACY directions respectively 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.

xr{-1, 1}

Indicates if the polarization orientation parameters are for a transmit signal (1) or for a receive signal (-1)

ampx, ampyfloat

E-field relative amplitude components in the ACX and ACY directions respectively

phasex, phaseyfloat

E-field phase components in the ACX and ACY directions respectively

Returns:

amph, ampvfloat

E-field relative amplitude components in the H and V directions respectively

phaseh, phasevfloat

E-field phase components in the H and V directions respectively
