Abstract
The estimation of time delay and Doppler difference of a signal arriving at two
physically separated sensors is investigated in this thesis. Usually, modified cross power
spectrum coupled with Doppler compensation is used to detect a common, passive signal
received at two separated sensors. Another successful approach uses the cross coherence
to achieve this goal. This thesis modifies these two techniques to model the Doppler
difference via an autoregressive (AR) technique. Analytical results are derived and experimentally
verified via a computer simulation. Performance at high and low signal to
noise ratios (SNRs) is examined.
