- 摘要:
- 2016年4月19-24日,在合肥市肥西县紫蓬山试验场开展了基于角反射器的定标试验,完成了地面静态条件下机载毫米波云雷达的标定。定标数据的分析表明,毫米波云雷达探测器在标准模式(脉冲宽度0.33 μs)和增强模式(脉冲宽度1.32 μs)两种模式下,测量得到的角反射器强度值与理论值的均方根误差分别为0.182 dB和0.197 dB。为下一步开展基于晴空海面的外定标实验打下基础。
- Abstract:
- On April 2016 19-24,the field test Zipeng corner reflector calibration test was carried out based on calibrated ground static conditions of airborne millimeter wave cloud radar in Feixi County of Hefei city. Calibration and analysis of the data shows that millimeter wave cloud radar detector in standard mode(pulse width is 0.33 μs)and enhanced mode(pulse width is 1.32 μs)under two modes, corner reflector strength measurement values obtained by the root mean square error and the theoretical values are 0.182 dB and 0.197 dB respectively. To lay the foundation for the next step the external calibration experiments was carried out based on clear sky sea.
