激光雷达不同于普通的雷达,它的优点是:(1)光的波长为微米级,用适中的天线尺寸就能提供微弧度的目标分辨率或者用很小的天线提供弧度的分辨率;(2)因为光频在等离子体云谐振频率外,光雷达能够跟踪如再入飞船和导弹等目标,但目前微波雷达却存在这个问题休斯研究实验室所研制的实验性激光雷
LIDAR differs from an ordinary radar in that it has the following advantages: (1) the wavelength of light is on the order of microns, the target resolution in micro radians can be provided with a moderate antenna size, or the radian resolution can be provided with a small antenna; 2) Because the optical frequency of the light at the plasma cloud resonant frequency, the light radar can track such as reentry spacecraft and missiles and other targets, but the microwave radar is present this problem Hughes Research Laboratory developed experimental laser thunder
