(Cornell H. Mayer, "Radio Emission of the Moon...)

In the observations at 4.3 mm ( Coates , 1959 a ) , the diameter of the antenna beam , 6 ' .7 , was small enough to allow resolution of some of the larger features of the lunar surface , and contour diagrams have been made of the lunar brightness distribution at three lunar phases .

Very recently , observations have been made at 8 - mm wave_length with a reflector 22 meters in diameter with a resultant beam width of only about 2 ' ( Amenitskii , Noskova , and Salomonovich , 1960 ) .

The half-intensity diameter of the antenna beam was about 9 ' , and the angle subtended by the moon included the entire main beam and part of the first side lobes .

The half-intensity diameter of the antenna beam was about 9 ' , and the angle subtended by the moon included the entire main beam and part of the first side lobes .

The antenna patterns and the power gain at the peak of the beam were both measured ( Mayer , McCullough , and Sloanaker , 1958 b ) , so that the absolute power sensitivity of the antenna beam over the solid_angle of the moon was known .

(Walter H. Buchsbaum, "Advances in Medical Electronics"...)

In medicine the frequencies are much higher , transducers and the sonar beams themselves are much smaller , and different scanning techniques may be used , but the principles involved are the same as in sonar .

The frequency used for these experiments is 15 mc. and the transducer is a specially cut crystal with an epoxy lens capable of providing beam diameters smaller than one millimeter .

The transducer itself moves the beam in a sector scan , just like a radar antenna , while the entire transducer structure is moved over a 90 - degree arc in_front_of the eye to `` look_into '' all corners .
