return_array_geographic_rotation

HSTB.kluster.modules.beampointingvector.return_array_geographic_rotation(maintx, mainrx)

Use the transmitter/receiver array orientations to build a rotation matrix between the geographic/array rel reference frame.

Returns rotation matrices at each time/beam, of shape (beam, rot_i, time, xyz)

<xarray.DataArray ‘getitem-82dd48467b1f4e8b4f56bbe5e841cc9f’ (beam: 182, rot_i: 3, time: 2, xyz: 3)>

dask.array<transpose, shape=(182, 3, 2, 3), dtype=float64, chunksize=(182, 3, 2, 1), chunktype=numpy.ndarray>

Coordinates:

* rot_i (rot_i) int32 0 1 2

* time (time) float64 1.496e+09 1.496e+09

* beam (beam) int32 0 1 2 3 4 5 6 7 8 … 174 175 176 177 178 179 180 181

* xyz (xyz) <U1 ‘x’ ‘y’ ‘z’

Parameters

• maintx (DataArray) – orientation vector for transmitter at time of transmit, 2dim of shape (time, xyz)

• mainrx (DataArray) – orientation vector for receiver at time of receive, 2dim of shape (time, xyz)

Returns

rotation matrices at each time/beam, of shape (beam, rot_i, time, xyz)

Return type

xr.DataArray
