Many solutions have been proposed for passive localization systems based on Doppler-shifted frequency measurement. Unfortunately, no closed-form solution exists to this problem. Successive searching method usually suffers from heavy computation. Moreover, initial estimation with enough accuracy is required to avoid local convergence. Though the searching dimension can be reduced to 2 by introducing some intermediate variables that are nonlinear functions of unknowns, the computations are still… CONTINUE READING
