How does monopulse tracking work?
A monopulse antenna is one method of realizing a tracking radar. The word “monopulse” implies that with a single pulse, the antenna can gather angle information, as opposed to spewing out multiple narrow-beam pulses in different directions and looking for the maximum return.
What is a tracking radar?
Tracking refers to a radar following the position of one or multiple targets in space. Before the tracking process, the radar has to detect targets and find their range, angular location, and sometimes velocity. The principle of tracking radar is to use the error signal to adjust the antenna’s pointing direction.
What are the advantages of monopulse radar over conical scan radar?
Angle accuracy is not affected by fluctuation in the echo amplitude. Angle accuracy is not affected by fluctuation in the echo amplitude. System performance is degraded by glint.
What is conical scan tracking radar?
Conical-scan receive-only (COSRO) The output of the multiplex device is a single RF signal and two position signals that indicate left/right and up/down. The COSRO technique does not transmit any signals that indicate the position of the rotating vane.
How do tracking and scanning radar differ?
The track while scan (TWS) is a mode of radar operation in which the radar allocates part of its power to tracking the target or targets while part of its power is allocated to scanning, unlike the straight tracking mode, when the radar directs all its power to tracking the acquired targets.
What is the meaning of monopulse?
The definition of monopulse in the dictionary is a radar transmitting a single pulse only or the single pulse itself. Other definition of monopulse is a sole laser power pulsation.
What is conical scan tracking?
Figure 1: At the conical scan the antenna traces a cone pattern around its central axis. Some older target tracking radars use the conical scan to determine the exact target direction.
How can I track my radar?
The Radar, which is used to track the path of one or more targets is known as Tracking Radar. In general, it performs the following functions before it starts the tracking activity. So, Tracking Radar tracks the target by tracking one of the three parameters — range, angle, Doppler frequency shift.
How is tracking achieved using radar?
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.
