摘要

雷达外部定标是获取未知目标雷达截面的重要手段。标定方法的选择与雷达站所处的环境密切相关。本文报道了一种利用有源雷达校准器(ARC)在渔船上对超高频岸基雷达进行标定的方法。发现海面对多径传播的影响不能像地面对多径传播的影响那样消除。在多径模型分析的基础上，本实验较好地解决了多径传播问题，标定精度控制在2dB。

Calibration measurement of shore-based radar with active reflector

Radar external calibration is an important means to obtain the radar cross section (RCS) of unknown target. The choice of calibration method is closely related to the ambient environment of the radar station. This paper reports a calibration measurement of the UHF-band shore-based radar with active radar calibrator (ARC) on a fishing boat. It was found that multipath propagation effect due to the sea surface could not be eliminated as due to the ground. Based on the analysis of multi-path model, our experiment solved the problem of multi-path propagation better, and the calibration precision is controlled at 2dB.
