| Abstract: |
| Objective To improve RSC measurement calibration accuracy of sea target based on millimeter wave. Methods Armed at the dynamic calibration problem of outfield RCS (radar cross section) dynamic measurement system for target on the sea, based on the passive relative calibration method given, influences of cloud clutter, atmospheric attenuation as well as sea surface and ground clutter in calibrating the millimeter wave RCS measurement system were analyzed in details. Results Measures such as attenuation correction and proper selection of proper meteorological condition for decreasing relative calibration error were proposed in combination with actual outfield measurement of the range. Conclusion Analysis based on millimeter wave sea target RCS measurement calibration and measures can greatly reduce influences of meteorological environment as well as sea surface and ground clutter on the system calibration in the millimeter wave outfield sea surface measurement and improve the system calibration accuracy. |
