Abstract:In China, there are several weather radars built in high mountains. Due to the high altitude and the curvature of earth, low level observation is limited if the conventional volume scan strategies (VCP12/VCP22) are adopted. At Changle Site, new volume scan strategies which adopt 0° or negative elevation angles bring lots of benefits for monitoring and warning severe weather, but also increase the chance of disadvantages, such as ground clutter, wave clutter, anomalous propagation (AP) and so on. This paper discusses the characteristics of strong AP clutter at Changle Site, introducing a method based on template matching to remove it. The method does not have any impact on new volume scan strategies, but can remove the strong AP effectively. Now the method is running in test, and to be used in the Radar Operational Software Engineering (ROSE).
