- 摘要:
- 随着中国对天气雷达需求的不断增长以及超大城市协同组网业务的深入推进,同频干扰杂波逐渐成为影响天气雷达数据质量和应用效果的重要挑战。研究采用X波段双偏振天气雷达,开展一系列同频异步干扰实验,收集在干扰条件下的实际I/Q数据。通过对这些数据进行细致的时频特征分析,设计一种二维滤波算法,有效减轻同频异步干扰对天气雷达性能的负面影响,显著提升抑制干扰和恢复气象目标的能力。研究初步成果表明,该算法在模拟数据和实际雷达数据中的应用均取得积极效果。
- Abstract:
- With the continuously increasing demand for weather radar in China and the deepening of collaborative network service in megacities, the co-frequency interference clutter has gradually become an important challenge affecting the data quality and application effect of weather radar. In this study, X-band dual polarized weather radar was used to carry out a series of co-frequency asynchronous interference experiments and collect actual I/Q data under interference conditions. Through detailed time-frequency feature analysis of these data, a two-dimensional space-temporal filtering algorithm is developed, which effectively reduces the negative impact of asynchronous interference on the performance of weather radar, and significantly improves the ability to suppress interference and restore meteorological targets. The preliminary results show that the algorithm has achieved positive results on both simulated data and actual radar data.
