However, conical scanning could only easily be used on an antenna with a single feed horn, which is only practical with microwave radars.
12.
Since the lobe is being rotated around the midline of the antenna, conical scanning is only really appropriate for antennas with a circular cross section.
13.
Conical scanning was similar in concept to lobe switching, but as the name implies it was operated in a rotary fashion instead of two directions.
14.
W�rzburg also used conical scanning, which gives a slowly rotating polarisation, so that it was affected by all of the strips, no matter their orientation.
15.
Early in the program it was realized that existing radar systems based on the conical scanning method did not supply the performance needed for a high-speed missile.
16.
If the lobes are closely spaced, this signal can produce a high degree of pointing accuracy within the beam, adding to the natural accuracy of the conical scanning system.
17.
Conical scanning was also adopted in 1941 for the Navy's 10 cm fire-control radar system, and it was used in the German W�rzburg radar in 1941.
18.
His inventions included contributions to Identification Friend or Foe ( IFF ) technology, conical scanning and 3-dimensional radar, gunfire and shell trajectory control, and deception systems.
19.
This led to the introduction of the SCR-584, which fit the entire radar system on a single trailer, added conical scanning, and was generally much more accurate and far easier to operate.
20.
Lovell's primary task during this period was developing a conical scanning system that improved the accuracy of the radar beam many times, enough to allow it to be used directly to lay the guns ( that is, about the same accuracy as optical instruments ).
