| 中文摘要: |
| 试验数据分析表明我国东南沿海海域是大气波导高概率发生区， 实时、 精确的折射指数预测预报是电子系统性能评估和系统设计的关键。通过大气折射率剖面的直接测量、 基于特定高度气象参数的理论预测、 GPS测量、 海杂波反演技术等测量、 预测预报技术的对比分析， 海杂波反演技术由于实时性、 保密性、设备简易等优点， 是一种极具潜力的大气波导环境预测技术。 |
| 英文摘要: |
| The experimental data showed that Southeast China Sea has a higher occurrence probability of atmospheric duct. Real-time and accurately forecasting and predicting the refractive index is the key factor to assess marine electronic weapon system performance and design appropriate system. By direct measurement, model prediction based on meteorological parameters, GPS measurements and refractivity from sea clutter inversion (RFC), comparison and analysis showed that RFC with real-time, confidential, and equipment-simple advantages is a promising technique for predicting atmospheric duct. |
