近年来,对风场的测量变得复杂起来,人们逐渐了解到天基风场测量的优越性。直到最近计量界才确信这种测量的实际可靠性。1987年是采用相干激光雷达来测量晴空风场二十周年纪念。为此美国航天局提出的地球观察系统(EOS)设计了一种CO_2激光雷达
In recent years, the measurement of the wind field has become more complicated, and people are gradually realizing the superiority of space-based wind field measurement. Until recently the metrology community was convinced of the actual reliability of such measurements. 1987 is the twentieth anniversary of the use of coherent laser radar to measure the wind field. To this end, the Earth Observation System (EOS) proposed by NASA has designed a CO 2 laser radar
