Advantages of doppler radar over other radar in tabular form
Answers
Answer:
A Doppler radar is a type of radar system which use Doppler effects to determine an object’s velocity data from distance. This is done by bouncing of microwave signals off the target and determine how the object’s motion alter the frequency of returned signals.
Advantages:
1. High-quality data: Doppler radar provide high-quality data compared to standard radars. 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.
3. Measure thunderstorm rotation: Doppler radar can measure thunderstorm rotation before the tornadoes occur. Airborne Doppler is used to studying the effects of tornadoes to large winter storms.
4. Lightweight: Doppler radars are lightweight in nature are able to remove stationary reflections and integrate signal over a long time span.
5. Improve range performance: Military systems use Doppler radar systems to support night combat vision. It can help improve range performance as well as reduce power.
6. Stabilization and navigation: Doppler radar determines the aircraft velocity, navigation and the stabilization of the aircraft by sending sinusoidal waves on to the earth’s surface. It then uses the frequency shift of the reflected waves to navigate the aircraft.
7. Determine the target range: Doppler radar determines the range of the target by measuring the time interval between the transmitted pulses of light and the echo from the target object.
8. Determine intensity of precipitation: Doppler radar enables is used in weather forecasting by improving the capability to discern air motions in a storm whereas conventional radar systems provide information about the location and the intensity of precipitation which is associated with the storm.
9. Determine wind shears: It helps meteorologists and scientists to detect any near-ground wind shears which can be dangerous when flying the aircraft. They can also forecast the severity of weather conditions in a certain location and improve the safety of the public and save lives.
10. Detect turbulence: Doppler radar systems in airline transport and business aircraft use pulse air processing to determine speed, direction, and velocity between targets. It also measures whether the movement in the atmosphere is towards the radar or away from the radar...
