Both the axis of Radar Antenna and the direction of target will coincide when the angular error is zero. There exists a feedback mechanism in the Tracking Radar, which works until the angular error becomes zero.
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.
Figure 1: radar principle. Figure 2: Block diagram of a primary radar. Transmitter The radar transmitter produces the short duration high-power rf pulses of energy that are into space by the antenna.
Duplexer The duplexer alternately switches the antenna between the transmitter and receiver so that only one antenna need be used.
This switching is necessary because the high-power pulses of the transmitter would destroy the receiver if energy were allowed to enter the receiver.
Receiver The receivers amplify and demodulate the received RF-signals. External Websites. Articles from Britannica Encyclopedias for elementary and high school students.

It works by radiating energy into space and monitoring the echo or reflected signal from the objects. It operates in the UHF and microwave range.
A radar is an electromagnetic sensor, used to notice, track, locate, and identify different objects which are at certain distances.
The working of radar is, it transmits electromagnetic energy in the direction of targets to observe the echoes and returns from them.
Here the targets are nothing but ships, aircraft, astronomical bodies, automotive vehicles, spacecraft, rain, birds, insects, etc.
Radar has its own transmitter which is known as a source of illumination for placing targets. Generally, it works in the microwave area of the electromagnetic spectrum that is calculated in hertz when frequencies extend from MHz to 40 GHz.
The essential components which are used in the radar. Radar undergoes quick development during the years the 40s to reach the requirements of the military.
It is still broadly used through the armed forces, wherever several technological advances have created. Simultaneously, radar is also utilized in civilian applications particularly in controlling air traffic, observation of weather, navigation of ship, environment, sensing from remote areas, observation of planetary, measurement of speed in industrial applications, space surveillance, law enforcement, etc.
If we select a shorter duration between the two clock pulses, then the echo signal corresponding to present clock pulse will be received after the next clock pulse.
Due to this, the range of the target seems to be smaller than the actual range. So, we have to select the duration between the two clock pulses in such a way that the echo signal corresponding to present clock pulse will be received before the next clock pulse starts.
Then, we will get the true range of the target and it is also called maximum unambiguous range of the target or simply, maximum unambiguous range.
Mathematically , it can be represented as. Long-range radar antenna , used to track space objects and ballistic missiles.
