Passive source localization using single hydrophone has received considerable attention in the last decade particularly in marine biological studies. If proven successful, it should find tremendous applications, both in military and civilian. Underwater vehicles such as gliders, AUVs, ROVs, torpedoes, mines, etc. seldom have more than one sensor fitted on them for carrying out reconnaissance/ threat...
Lidar has proven to be an effective instrument for obtaining high resolution profiles of atmospheric aerosols. In this work we present the characteristics of the atmospheric aerosols derived using the range dependent lidar ratio values at the two tropical stations namely Trivandrum (8.330 N, 770 E), India and Gadanki (13.50 N, 79.20 E), India. Summer aerosol properties at the two stations are studied...
