| Abstract: |
| Objective To improve the environmental adaptation of ionospheric radio from space surveillance radar. Methods When the VHF-L radio propagated through the ionosphere, the radar signal was incoherently scattered by the ionospheric free electron and the ionosphere information was included in the scattered echo. Combined with the radar equation and ionospheric target property, the radar parameter setting and beam scanning mode were investigated by the incoherent scatter mechanism of ionosphere. The ionospheric echo power, auto-correlation function and electron expression were introduced. And the raw sampling data from one space radar with high power was processed by using the Matlab routine and the ionospheric echo and electron density were obtained. Results Conditions for the ionospheric incoherent scatter from the space surveillance radar was described. ionospheric echo and The electron density varied in accordance with the ionospheric characteristic. Conclusion It is feasible to derive the ionospheric electron density from the scattered echo of space surveillance radar with high power in VHF-L band, which might be a new method for ionospheric environment measurement and propagation correction. |
