A photonic approach for both wideband Doppler frequency shift (DFS) measurement and direction ambiguity resolution is proposed and experimentally demonstrated. In the proposed approach, a light wave from a laser diode is split into two paths. In one path, the DFS information is converted into an optical sideband close to the optical carrier by using ...

Passive localization from Doppler shifted frequency measurements
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991An efficient search scheme for an underwater radiating source is developed by introducing intermediate variables which are products of some of the unknowns. The search dimension is only two, in x-y position, instead of five. The resultant intermediate equations become linear and are easier to solve; the major calculation at each grid point requires an ...
