Abstract

Summary form only given. Cross-wind speed was measured, using a one-station scheme, over a flat sandy beach strip, parallel to the Mediterranean seashore. A diffusive white target distanced 1.5 km away was illuminated with a 5 mJ, Q-switched Nd:YAG laser beam with a rep-rate of 500 Hz. The laser spot on the target had a diameter of about 50 cm. The reflected beam was imaged, near the laser, onto a linear array detector of 50/spl times/250 /spl mu/m element size by a f-1000 mm D=91 mm, Cassegrain lens.

利用大气湍流进行远程侧风测量
只提供摘要形式。在与地中海海岸平行的平坦沙滩上,采用单站方案测量了横向风速。用频率为500 Hz的5 mJ调q Nd:YAG激光束照射1.5 km外的漫射白色目标。目标上的激光光斑直径约为50厘米。通过f-1000 mm D=91 mm的卡塞格伦透镜,将反射光束在激光器附近成像到元件尺寸为50/spl倍/250 /spl μ /m的线阵探测器上。
