Spectrum widths, one of the three moments measured and displayed by the new generation weather surveillance radar, provide the observation to the average radial velocity of rain particles caused by shear, turbulence and sample velocity's accuracy. 速度谱宽作为新一代天气雷达的三个基本产品之一,它可提供由于风切变、湍流和速度样本质量引起的平均径向速度变化的观测。
Design of Weather Channel in ATC Primary Surveillance Radar 航管一次监视雷达中气象通道的设计
Study on Weather Data Processing of Primary Surveillance Radar 一次雷达气象数据处理研究
For design of weather channels in ATC primary surveillance radar ( PSR ), it is difficult to obtain the weather intensity and Doppler information as true as Possible without loss of the performance of detection of airplane. 保证在飞机探测性能不受损失的前提下,尽可能真实提取气象的强度和多普勒信息,是航管一次监视雷达气象通道的设计难点。
