Compact LIDAR for continuous monitoring of atmospheric state variables

Atmospheric effects, which may change quickly in littoral regions, can impact the performance of a variety of electro-magnetic and electro-optical based Navy systems. Marine aviation, especially of unmanned platforms, will also benefit from increased observation and improved prediction of the atmosphere. Improving the capability for monitoring the atmosphere will increase the effectiveness of many Navy systems. Automated systems will enable reduction of manpower. Physical Sciences Inc., along with its subsidiary Q-Peak Inc., proposes to develop an advanced, compact Raman Lidar (Light Detection and Ranging) capable of continuous, automated profiling of atmospheric state variables, including temperature, relative humidity, and pressure to ranges of 1500 m at a spatial resolution of 1 m and temporal resolution of several minutes. A state-of-the-art miniaturized laser design enables a sensor footprint on the order a few cubic feet. The Phase I program will develop designs for the lidar. The Phase I Option Program will address beam steering optics and accommodation of ships motion, as well as additional engineering for the electronics for the laser. The Phase II Program will develop and shore test an engineering prototype sensor. The Phase III Program will integrate and test the prototype on a designated Navy platform.
