CRLB for joint estimation of TDOA, phase, FDOA, and Doppler rate
The Journal of Engineering, 2019 To avoid decline of FDOA estimation precision caused by relative Doppler companding, Doppler rate has to be considered and estimated jointly with TDOA, phase, and FDOA. However, CRLB of the joint estimation is still unclear.
