Technical field of observation and inspection method for accumulated snow depth measurement with multiple sensors

The invention discloses an observation and inspection method for accumulated snow depth measurement with multiple sensors. The method uses multiple means to detect and verify the basic performance of a test object and determine the precision, solves the problems existing in instrument calibration, measures the measurement deviation of the known wind direction and wind speed influence, determines whether the measurement deviation is within the range of a functional specification demand book provided by a manufacturer or not, and determines whether the measured snow depth sensor meets the requirements of the functional specification demand book or not due to the influence of environment temperature change during operation. 本发明公开了一种具有多传感器的积雪深度测量的观测检验方法，该方法使用多种手段，检测与验证测试对象的基本性能并确定精度、仪器校准存在的问题，测量已知风向、风速影响的测量偏差以及确定测量偏差是否在制造商提供的功能规格需求书范围内，确认被测雪深传感器运行期间受环境温度变化的影响是否满足功能规格需求书要求。
