sarkit.cphd.compute_t_ref

compute_t_ref(xmt, rcv, srp, txc, trc)

Compute the reference times for the given collection geometry parameters.

Parameters:

xmt(…, 3) array_like: Transmit APC positions at times txc in ECF coordinates with X, Y, Z components in meters in the last dimension.
rcv(…, 3) array_like: Receive APC positions at times trc in ECF coordinates with X, Y, Z components in meters in the last dimension.
srp(…, 3) array_like: Stabilization Reference Point positions in ECF coordinates with X, Y, Z components in meters in the last dimension.
txc(…) array_like: Time the center of the pulse is at the Transmit APC in seconds.
trc(…) array_like: Receive time for the center of the echo from the SRP relative to Collection Start Time in seconds.

Returns:
