What is true for electromagnetic waves?
Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. They are also perpendicular to the direction of the EM wave.
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 tracking in 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. Target detection. Range of the target. Finding elevation and azimuth angles.
How do tracking and scanning radar differ?
Search radars search the targets within a given volume of a solid angle and within a given slant range in a specified amount of time. The tracking radar continuously tracks the target and determines the position or direction of a target in range, azimuth angle, elevation angle, and velocity.
Which of the following will be the best scanning system for tracking after a target has been acquired?
Conical
What is automatic detection and tracking radar?
classification of radar In radar: Interference. …not as easily ignored by automatic detection and tracking systems, however, and so some method is usually needed to recognize and remove interference pulses before they enter the automatic detector and tracker of a radar.
How does a radar detect direction?
A radar system has a transmitter that emits radio waves known as radar signals in predetermined directions. When these signals contact an object they are usually reflected or scattered in many directions, although some of them will be absorbed and penetrate into the target.
What limits the maximum range of a surface search radar?
Doubling the peak power increases the range capabilities by about 25 percent. The longer the pulse length, the greater is the range capability of the radar because of the greater amount of energy transmitted. The pulse repetition rate (PRR) determines the maximum measurable range of the radar.
What are the factors affecting the radar range?
The maximum range of a radar system depends in large part on the average power of its transmitter and the physical size of its antenna. (In technical terms, this is called the power-aperture product.) There are practical limits to each. As noted before, some radar systems have an average power of roughly one megawatt.
