conical scanning

The two views result from the instrument's conical scanning mechanism.

Using a technique known as conical scanning, this could be further reduced to well under a degree, more than enough to directly lay the guns.

In particular, conical scanning radars required some time to settle on an accurate track.

This is combined with conical scanning or monopulse to improve track reliability.

Older systems rely on conical scanning rather than monopulse.

In practice, the systems used additional information from the signal, such as conical scanning, to more accurately calculate the centerline.

To arrange conical scanning on such a system would require all of the dipoles to be moved, an impractical solution.

It was equipped with a conical scanning feed, providing higher resolution and making automatic tracking easier.

The solution to providing much higher angular accuracy was already known, a technique known as conical scanning.

Squint is also required in conical scanning.

Conical scanning is not considered to be a form of monopulse radar, but the following summary provides background that can aid understanding.

Jamming resistance is greatly improved over conical scanning.

Truly practical designs did not become possible until the introduction of conical scanning and miniaturized vacuum tubes during the war.

These were combined with techniques developed during the war to improve accuracy of otherwise inherently inaccurate radar systems, especially the conical scanning system.

The onboard electronics were based on a simple analog design, with a homing conical scanning radar sensor.

Instead of simply using a smaller Yagi antenna, the system was paired with a new parabolic dish which allowed for conical scanning.

One used spiral-scan to search for targets, while the second used conical scanning for tracking at close range.

Würzburg also used conical scanning, which gives a slowly rotating polarisation, so that it was affected by all of the strips, no matter their orientation.

This avoids problems in decoding conventional conical scanning systems, which can be confused by rapid changes in signal strength.

Conical scanning addresses this problem by "moving" the radar beam slightly off center from the antenna's midline, and then rotating it.

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.

The most common form is an adaptation of conical scanning radar which compares the return from two directions to directly measure the location of the target.

Conical scanning: The radar beam is rotated in a small circle around the "boresight" axis, which is pointed at the target.

However, conical scanning could only easily be used on an antenna with a single feed horn, which is only practical with microwave radars.

The concept was used only briefly, and was almost completely replaced by conical scanning systems by the end of World War II.
