摘要： A platform for a handheld wind profiler includes a housing containing a three-axis magnetic compass module generating a compass signal, including the orientation of the housing relative to magnetic north at a time. A two-axis inclinometer module generates a inclinometer signal including the orientation of the housing relative to a horizontal plane at the time. A GPS module generating a GPS signal indicating a time and position solution including a terrain position of the housing based upon the time. A processor receives a first velocimeter signal at the time from at least one laser Doppler velocimeter. The velocimeter signal includes a first radial velocity of a first wind-borne aerosol and a first orientation of the at least one laser Doppler velocimeter relative to the housing. The processor resolves the first velocimeter signal to determine an orientation of the at least one laser Doppler velocimeter relative to the terrain position.
