摘要
高空降雨云层作为一种气象目标,也是对雷达波的吸收体,降雨路径上造成的衰减会对气象信息的探测带来严重的影响。文中设计了一种具有降雨路径补偿的机载雷达气象方式,引入了降雨区衰减和降雨率的关系,将近端降雨区的衰减量作为参数解算远端降雨率,并对其原理、算法和实现方法作了详细阐述。通过对实测数据处理验证表明:具有降雨路径补偿的气象方式可以更准确地反映气象环境,保证飞行安全。
Rain upper air is a weather target, also is an absorber for radar wave. Attenuation of rain has a bad influence for detection of weather information. In this paper, a weather operation mode with compensation of rain for airborne radar is designed. The relation of attenuation of rainfall section and rain rate in introduced. The attenuation of near rain section is a parameter used for calculation of far rain rate. The principle ,arithmetic and realization method are discussed in detail. It is indicated that this mode can provide the weather environment and security of fly more veraciously bv Drocessing the measuring data.
