- r_rdot_to_ground_plane_bi(look, scp, projection_sets, gref, ugpn, *, delta_gp_gpp=0.01, maxiter=10)
Project along bistatic contours of constant average range and range rate to an arbitrary plane.
- Parameters:
- look{+1, -1}
+1 if SideOfTrack = L, -1 if SideOfTrack = R
- scp(3,) array_like
SCP position in ECEF coordinates (m).
- projection_sets
ProjectionSetsBi Ensemble of Center of Aperture projection sets to project.
- gref(3,) array_like
Ground plane reference point with ECEF (WGS 84 cartesian) X, Y, Z components in meters.
- ugpn(3,) array_like
Unit normal vector to ground plane with ECEF (WGS 84 cartesian) X, Y, Z components in meters.
- delta_gp_gpp
float, optional Ground plane displacement threshold for final ground plane point in meters.
- maxiter
int, optional Maximum number of iterations to perform.
- Returns:
- g(…, 3)
ndarray Array of ground plane points with ECEF (WGS 84 cartesian) X, Y, Z components in meters in the last dimension.
- delta_gp
ndarray Magnitude of the displacement from estimated point to the precise intersection of the target R/Rdot contour.
- successbool
Whether or not all displacement magnitudes,
delta_gpare less than or equal to the threshold,delta_gp_gpp.
