Что (кто) такое SAGE radar stations - определение


SAGE radar stations         
  • SAGE radar stations were grouped by Air Defense Sectors (Air Divisions after 1966).  The SAGE System networked the radar stations in over 20 of the sectors using AN/FSQ-7 centrals in Direction Centers.
WIKIMEDIA LIST ARTICLE
The SAGE radar stations of Air Defense Command (Aerospace Defense Command after 1968) were the military installations operated by USAF squadrons using the 1st automated air defense environment (Semi-Automatic Ground Environment) and networked by the SAGE System, a computer network. Most of the radar stations used the Burroughs AN/FST-2 Coordinate Data Transmitting Set (CDTS) to automate the operator environment and provide radar tracks to sector command posts at SAGE Direction Centers (DCs), e.
Sage (philosophy)

Sages; Sage (Sophos); Sage philosophy; Sage (sophos); Sophos (philosophy); Sagdom
A sage (, sophos), in classical philosophy, is someone who has attained wisdom. The term has also been used interchangeably with a 'good person' (, agathos), and a 'virtuous person' (, spoudaios).

  • 3D Doppler radar spectrum showing a [[Barker code]] of 13
  • A [[Chain Home]] tower in Great Baddow, Essex, United Kingdom
  • Change of [[wavelength]] caused by motion of the source
  • Experimental radar antenna, US [[Naval Research Laboratory]], Anacostia, D. C., from the late 1930s (photo taken in 1945)
  • AS-3263/SPS-49(V) antenna (US Navy)
  • echoes]] from a target cause ghosts to appear.
  • [[Phased array]]: Not all radar antennas must rotate to scan the sky.
  • Pulse-Doppler signal processing. The ''Range Sample'' axis represents individual samples taken in between each transmit pulse. The ''Range Interval'' axis represents each successive transmit pulse interval during which samples are taken. The Fast Fourier Transform process converts time-domain samples into frequency domain spectra. This is sometimes called the ''bed of nails''.
  • Echo heights above ground<br /><math>H=\left (\sqrt{r^{2}+(k_{e}a_{e})^{2}+2rk_{e}a_{e}sin(\theta _{e})} \right )-k_{e}a_{e}+h_{a}</math> <br />Where : <br />&nbsp;&nbsp;r : distance radar-target <br />ke : 4/3 <br />ae : Earth radius <br />θe : elevation angle above the radar horizon <br />ha : height of the feedhorn above ground
  • Slotted waveguide antenna
  • Radar components
  • Pulse radar: The round-trip time for the radar pulse to get to the target and return is measured. The distance is proportional to this time.
  • Commercial marine radar antenna. The rotating antenna radiates a vertical fan-shaped beam.
  • Surveillance radar antenna
  • Continuous wave (CW) radar. Using frequency modulation allows range to be extracted.
  • The first workable unit built by [[Robert Watson-Watt]] and his team
  • Memorial plaque commemorating Robert Watson-Watt and [[Arnold Wilkins]]
