31undersea exploration — Introduction the investigation and description of the ocean waters and the seafloor and of the Earth beneath. Primary objectives and accomplishments Included in the scope of undersea exploration are the physical and chemical… …
32Transmission line — This article is about the radio frequency transmission line. For the power transmission line, see electric power transmission. In communications and electronic engineering, a transmission line is a specialized cable designed to carry alternating… …
33SHARAD — (Mars SHAllow RADar sounder) is a subsurface sounding radar embarked on the Mars Reconnaissance Orbiter probe. It complements the MARSIS instrument on Mars Express, providing lower penetration capabilities (some hundred meters) but much finer… …

35Acoustic Doppler Current Profiler — Head of an ADCP with the four transducers ADCP view ahead, mo …
36coherent oscillator — An oscillator, in MTI (moving target indicator) radars, providing a coherent reference by which the radio frequency phase of a received pulse may be compared with that of a transmitted pulse …
37echo box — An apparatus designed to test and calibrate a radar set. The transmitted pulse is fed into the echo box instead of the radar antenna. The echo box then produces a delayed return pulse, the intensity of which gradually falls at a certain rate.… …
38Round-trip delay time — In telecommunications, the term round trip delay time or round trip time (RTT) has the following meanings: # The elapsed time for transit of a signal over a closed circuit, or time elapsed for a message to a remote place and back again. # In… …
39J-display — A modified A scope in which the time base is circular. The display appears as a circle with the transmitted pulse at the top. The scanning proceeds clockwise at a rapid rate. Echoes appear as radial pips. The greater the distance or range to the… …
40A-scope — A basic radar scope in which the target range is a measure of the distance at which the target blip appears from the beginning of the scope. Often, the transmitted pulse is allowed to show as a large vertical deflection at the beginning of the… …
