advantage and disadvantage of radar 5 to 6 point
Answers
Advantages of RADAR
1. RADAR can penetrate mediums such as clouds, fogs, mist and snow. The signals used by RADAR technology are not limited or hindered by snow, clouds or fogs. This means that even in the presence of these adverse conditions, data will still be collected.
2. RADAR signal can penetrate insulators. Materials that are considered insulators such as rubber and plastic do not hinder RADAR signals from collecting data. The signals will penetrate the materials and capture the necessary data require.
3. It can give the exact position of an object. RADAR systems employ the use of electromagnetic to calculate the distance of an object and its exact position on the earth’s surface or space.
4. It can determine the velocity of a target. RADAR systems have the capability of calculating the velocity of an object in motion. Besides knowing its location, you will also have data regarding the velocity of the object.
5. It can measure the distance of an object. RADAR systems work by measuring the exact distance of an object from the transmitter.
Disadvantages of RADAR systems
1. RADAR takes more time to lock on an object. Since radio signals travel freely in air and space, it takes more time to get to the object and back.
2. RADAR has a wider beam range (Over 50ft Diameter). The beam range for RADAR is quite wide and not target specific.
3. It has a shorter range (200ft). Unlike LiDAR, RADAR signals operate at a limited range of 200ft.
4. It cannot track if an object is decelerating at more the 1mph/s. If an object is in motion, it may be a challenge for RADAR systems to collect data from the object.
5. Large objects that are close to the Transmitter can saturate the receiver. The radio signals work best when the object is further away from the receiver and not closer.

5. It can measure the distance of an object.
6. It can tell the difference between stationary and moving targets.
7. RADAR signals do not require a medium of transportation.
8. RADAR signals can target several objects simultaneous
9.It allows for 3D Imaging based on the various angles of return.
10. It is wireless and does not rely on wire connectivity.
11. It is cheaper as compared to other systems.
12. High operating frequency allows for storage of large amounts of data.
13. It covers a wider geographical area.
14. It allows for repetitive coverage. RADAR systems are not limited to single coverage of a target.
15. Easy data acquisition at different scales.
16. It is fast if the area is not too large.
17. It has several industrial applications.
18. Cheap and fast method of calculating base maps when no detailed survey is required.
19. It can get data from some of the remotest areas of the planet.
20. It is economical when doing small-scale map revision.

6. Readings may be falsified if the object is handheld.
7. RADAR can be interfered by several objects and mediums in the air.
8. It cannot distinguish or resolve multiple targets.
9. It cannot differentiate the color of the object.
10. It cannot resolve targets that are deep in the sea.
11. It cannot resolve targets that are obstructed by a conducting material.
12. It cannot resolve the type of the object.
13. It is not very accurate.
14. It can be interrupted with other signals.
15. It is not very stable and is susceptible to external interference
16. It can be oversensitive.
17. It cannot be used beyond the ionosphere.
18. It can be expensive if used in small areas especially if it is one time use
19. It requires specialized training to analyze the data.
20. The data provided by RADAR systems is usually not complete.
