What are the drawbacks in sequential Lobing tracking?

There are two disadvantages of the use of either sequential lobing or conical scanning. The first and most obvious is that the motion of the Antenna Tracking System is now more complex, and additional servomechanisms are required.

What are the types of tracking radar?

Tracking radars are classified by how the tracking errors are developed. The principal tracking schemes include lobe switching, conical scan and monopulse tracking. Lobe switching: In the lobe switching mode, the antenna beam is switched alternately between two positions.

What is simultaneous Lobing?

Introduction: The names simultaneous lobing and mono pulse are used to describe those tracking techniques which derive angle-error information on the basis of a single pulse.

How does a tracking radar work?

A radar system detects other aircraft, ships, or other objects and the speed and direction in which they travel by sending out a pulse of high-frequency electromagnetic waves. This pulse goes out ahead of the aircraft until it encounters an object and reflects off of it.

What is Monopulse technique?

Monopulse radar is a radar system that uses additional encoding of the radio signal to provide accurate directional information. The name refers to its ability to extract range and direction from a single signal pulse. The monopulse method does not require that the measured signals are pulsed.

What is monopulse tracking radar?

Monopulse radar is a radar system that uses additional encoding of the radio signal to provide accurate directional information. The name refers to its ability to extract range and direction from a single signal pulse. Monopulse radar systems can be constructed with reflector antennas, lens antennas or array antennas.

What is conical scan tracking radar?

The Conical Scan You can generate a conical scan pattern, as shown in figure 1, by using a rotating feed driven by a motor in the housing at the rear of the dish. The axis of the radar lobe is made to sweep out a cone in space; the apex of this cone is, of course, at the radar transmitter antenna or reflector.

What can radar pick up?

Part of this beam of energy bounces back and is measured by the radar, providing information about the object. Radar can measure precipitation size, quantity, speed and direction of movement, within about 100 mile radius of its location.

What is sequential lobing and Sequential Switching?

Now, let us discuss about these two techniques one by one. If the Antenna beams are switched between two patterns alternately for tracking the target, then it is called sequential lobing. It is also called sequential switching and lobe switching. This technique is used to find the angular error in one coordinate.

What is sequential lobing in antenna?

As shown in the figure, Antenna beams switch between Position 1 and Position 2 alternately. Angular error θ is indicated in the above figure. Sequential lobing gives the position of the target with high accuracy. This is the main advantage of sequential lobing.

What is the difference between sequential lobing and conical scanning?

Angular error θ is indicated in the above figure. Sequential lobing gives the position of the target with high accuracy. This is the main advantage of sequential lobing. If the Antenna beam continuously rotates for tracking a target, then it is called conical scanning. Conical scan modulation is used to find the position of the target.
