| Abstract: | The acquisition of accurate frequency out of the complex radar pulse signal is a key technology in the passive locating and tracking system of single site. The frequency extraction of the coherent pulse signal in additive noise was studied, and a new algorithm was proposed for the frequency estimation. By simulation, it is shown that this algorithm has higher estimating precision and lower computation, which is very effective. |
| Keywords: | passive localization coherent pulse signal frequency estimation least square estimation |
