| Abstract: | The inversion of atmospheric refractivity profile from radar′s sea clutters based on five-parameter method which were carried by radar clutters in the propagation paths was analyzed.The experiments were carried out in some Chinese sea areas,and the same time when surface of the waveguide and evaporation waveguide existed was set as an example.Experiment results show that the value of the inversion and actual measurement are in the effective range,and the inversion of atmospheric refractivity profile from the radar′s sea clutters based on five-parameter method is applicable to Chinese sea areas,which overcomes the difficult of atmospheric refractivity profile measurement in the condition of sea area with real-time,convenient,and easy characteristics. |
| Keywords: | sea elutter atmospheric refraetivity profile five-parameters method inversion experiment |
