Paper Abstract

A comparative transmissometer has been developed for evaluating the simultaneous transmission characteristics for near ocean surface transmissions in the 3 - 5 micrometers and 8 - 12 micrometers bands. this transmissometer is a special purpose instrument designed for simultaneously measuring the changes in transmission of the 3 - 5 micrometers and 8 - 12 micrometers transmission bands. the transmissometer has been operated over the San Diego Bay, California, to determine the transmission characteristics for near ocean propagation paths. Observed propagation characteristics for both the 3 - 5 micrometers and 8 - 12 micrometers bands are compared and discussed as a function of existing sea states and meteorological conditions. The observed transmission characteristics for the two wave bands are compared with LOWTRAN calculations. Rapid fluctuation in received signal strength, their power spectra, and correlation coefficients are also discussed.
