1. what is a radar? cite at least three examples of a radar
Answer:
Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.
Examples of it:
•Bistatic radar.
•Continuous-wave radar.
•Doppler radar.
2. it takes 7.25×19^(5) seconds for the radar to reach the plane and return to the radar. How far is the radar's detection in kilometers?

radar, electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them. The targets may be aircraft, ships, spacecraft, automotive vehicles, and astronomical bodies, or even birds, insects, and rain. Besides determining the presence, location, and velocity of such objects, radar can sometimes obtain their size and shape as well. What distinguishes radar from optical and infrared sensing devices is its ability to detect faraway objects under adverse weather conditions and to determine their range, or distance, with precision.
3. •list down the difference between a RADAR and LASER.•which has more advantage between RADAR and LASER? explain your answer.•list down some uses of RADAR and LASER.
Answer:
Explanation:
RADAR
Device that tracks and fixes the location of targets at a distance using radio waves and operates on the theory of radio echoes.
LASER
Device that makes light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
-Laser. It uses light which is much faster than radio waves.
-Sea navigation, stateline directions, CD recording, spectroscopy, barcode, scanning, etc.

10. ano ang sonars at radars
Answer:
SONAR vs RADAR | difference between SONAR and RADARThis page compares SONAR vs RADAR and mentions difference between SONAR and RADAR. SONAR stands for SOund Navigation And Ranging and RADAR stands for RAdio Detection And Ranging.Introduction:Both the systems are used for detection of objects, but at different places. Sonar does detection under water, whereas Radar does it above the land or sea. The principle of operations of both sonar and radar is same but uses different wave types.11. whats the type of radar wave
Answer:
The Radar, which operates with continuous signal or wave is called Continuous Wave Radar
12. Underwater sonars at radars *
Answer:
SONAR waves (compression waves) travel through water at much slower pace, the speed of sound. By measuring the time it takes for the signals to travel to the target and to return echoes, both RADAR and SONAR systems are capable of accurately determining the distance to their targets.
Explanation:
Brain lest13. What is the meaning of RADAR?
a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects, by sending out pulses of high-frequency electromagnetic waves that are reflected off the object back to the source.
14. how are microwaves used in radar?
Answer:
Explanation:
In police radar, a radar gun sends out short bursts of microwaves. The microwaves reflect back from oncoming vehicles and are detected by a receiver in the radar gun. The frequency of the reflected waves is used to compute the speed of the vehicles
15. Radio Detection and Ranging (RADAR)
Answer:
Radar plays a major role in advanced driver assistance systems (ADAS) now being included in most new vehicles and in the forthcoming self-driving cars and trucks.

16. what are meanings RADAR
Answer:
a system for detecting the presence, direction, distance, and speed of aircraft, ships, and other objects, by sending out pulses of high-frequency electromagnetic waves that are reflected off the object back to the source.
1 : a device or system consisting usually of a synchronized radio transmitter and receiver that emits radio waves and processes their reflections for display and is used especially for detecting and locating objects (such as aircraft) or surface features (as of a planet)
17. underwater sonars at radars
Answer:
S.O.N.A.R, an acronym for “sound navigation and ranging,” is a similar system to radar in terms of transmitting and receiving waves through pulses to determine distance and speed. However, it functions through the use of sound waves and is highly effective underwater.

Answer:
Radio Detection and Ranging.
Explanation:
Radar is the acronym of the answer
Answer:
RAdio Detection And Ranging
Explanation:
The term "Radar" itself was coined in 1940 by the United States Navy, as an acronym for "RAdio Detection And Ranging." Radar is pretty special - an MRI scan uses a form of radar to look inside the human body, while NASA used it to calculate the distance between the earth and other planets
19. Explain why you shouldn't use radar inconspicuous targets as reference points for Parallel Index Lines on the radar
Explanation:
While a ship follows course to steer, parallel indexing ensures it always remains at a fixed distance from a hazard. Thus parallel indexing is a method to alert mariner that he has come close to a navigational hazard

25. type of em wave radar
Answer:
Radar uses radio waves which are electromagnetic waves and travel at a speed of 300,000,000 m/s.
mark me if you satisfied
Answer:
Any electromagnetic wave can be used in radar. The most commonly used radar waves have wavelengths between about 1 centimeter (30 GHz) to about 1 meter (300 MHz), but there are some radars using much larger wavelengths (up to about 50 meters) and much smaller wavelengths (well under a millimeter). Laser range-finders used for surveying are a kind of radar, and use infrared or optical frequencies — the wavelength is on the order of 1 micron (a thousandth of a millimeter). GPS can be thought of as a kind of radar; the wavelength of GPS is around 20 cm.

27. What is Doppler radar?
Answer:
What is Doppler radar??
Explanation:
A Doppler radar is a radar that uses the Doppler effect to produce velocity data about objects at a distance
Question:What is Doppler radar?
Answer:A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
____________________________
Explanation:____________________________
Equation:
The Doppler- Effect is the apparent change in frequency or pitch when a sound source moves either toward or away from the listener, or when the listener moves either toward or away from the sound source. Derivation of the Doppler-frequency formula.
d(φ) = - 4π · vr
d(φ) = - 4π · vrdt λ
____________________________
Origin:
Doppler radar gets its name from Christian Andreas Doppler, an Austrian physicist. Doppler first described how the observed frequency of light and sound waves was affected by the relative motion of the source and the detector in 1842.
____________________________
Pros and cons:
Doppler radar is used by a meteorologist to diagnose rainfall as well as provide data on the flow of wind in the atmosphere. 2. Accurate data: It can accurately predict how severe a thunderstorm will be and ensure a warning is issued on time. It can accurately forecast changes in the wind and the flow of wind
