Acoustic transmitter....-A transmitter of acoustic energy which propagates that energy in a directional manner is described. An acoustic signal generator is connected at one end of an acoustic transmission line which exhibits a certain characteristic impedance. The line has a number of ports spaced along its length.... acoustic energy is partitioned evenly at each port so as to define an array of equal strength radiators having directional acoustic signal propagating characteristics. 2, record 1, English, - acoustic%20transmitter

The POLDER(Polarization and Directionality of the Earth's Reflectances) instrument will observe the polarization, directional and spectral characteristics of the solar light reflected by aerosols, clouds, oceans and land surfaces. POLDER is a push broom, wide field of view, multi-band imaging radiometer/polarimeter developed by CNES. Multi-angle viewing is achieved by the along-track migration at the spacecraft velocity of a quasi-square footprint intercepted by the total instantaneous 114-degree wide field of view. This footprint is partitioned into 242x274 elements of quasi-constant 7kmx6km resolution, imaged by a CCD matrix in the focal plane. 2, record 6, English, - polarisation%20and%20directionality%20of%20the%20Earth%27s%20reflectances
