pencil beam वाक्य

The " Blackwood "-class ships had the same sonar suite as the larger s where the Limbo mortars were controlled by three sonars, the Type 174 search set, Type 162 target-classification set and the Type 170'pencil beam'targeting set to determine the bearing and depth of the target.
The radar operates as a medium-to high-PRF pulse-Doppler, solid-state radar, in E / F-band ( 3 GHz ), incorporating 192 two-way transmit / receive modules that combine to produce a pencil beam, steered as required within the operating 150?sector each side of the aircraft ( one side at a time ).
This acoustic scattering is analogous to the scattering of the light from a car's headlights in fog : a high-intensity pencil beam will penetrate the fog to some extent, but broader-beam headlights emit much light in unwanted directions, much of which is scattered back to the observer, overwhelming that reflected from the target ( " white-out " ).
The main difference is that in HT a narrow intensity modulated pencil beam is delivered from a rotating gantry while the patient is simultaneously moved through the bore, compared to the much wider intensity modulated beam and static patient in conventional IMRT . HT units are therefore better able to target treatment sites throughout the body without a pause for the patient to be moved and set-up differently.
