What is the advantage and disadvantage of increased pulse rate?
If you have an increased pulse rate it means that you are exercising you heart more often meaning that you have a chance of living longer because your heart is stronger but if you over work your heart then you will risk heart failure (if you have a weak heart)!
What is the big deal about Doppler radar?
Early radar used radio interference to detect movement in the air of objects that would shift the appearance of the received waves. The directional high frequency radar was invented by the British. It sent out a large pulse of energy and timed its return to the receiver. That time divided by two was the distance to the object. Doppler radar sends out pulses of radio waves and measures their phase relationship to watch an objects motion and density in detail.
What is a short length of wave that travels?
This is often called a "pulse".This is often called a "pulse".This is often called a "pulse".This is often called a "pulse".
What is gram pulse?
gram pulse is a pulse which is yellow in colour when a gram is broken it separate itself into two parts and we eat it and named it gram pulse
What does a pulse plethysmograph measure?
A pulse plethysmograph is also known as a pulse volume recorder. A pulse plethysmograph measures the oxygen saturation level or SpO2.
What are the advantages of pulse position modulation?
Pulse position modulation offers high noise immunity, efficient use of bandwidth, and easy implementation with digital circuits. This modulation technique is particularly useful in applications requiring high data transmission rates and reliable communication in noisy environments.
What is the advantage of pulse tig welding?
produces extremely straight and even welds
What is the advantage of timing full minute to find your pulse?
For the perfect evaluation of heart beat.
What are the limitations of Moving Target Indicator in Pulse Doppler Radar?
1)antenna scanning modulation is time oriented 2)internal modulation of clutter3)system instability
What is the advantage of timing for a full minute to find your pulse?
The longer you time for the more accurate your measurement will be
What is the medical term meaning measuring blood pressure?
Pulse is measured as the number of times a heart beats per minute.
When you were palpating the various pulse points which appeared to have the greatest amplitude or tension?
The aortic, at the chest
What is radar ranging?
Radar Ranging is an Activity of a RADAR system to measure range of a particular object from the RADAR's own location the object can be aircrafts, ships or other objects like buildings. Usually Ranging is done by means of transmitting a pulse and receive echoes from it where the range is measured from time differences(or Delay) between departure and arrival of pulse , this ranging method is called as "Pulse Delay Ranging" Other ranging method is Doppler based ranging where range is measured by means of Doppler effect EDIT- it seems i need to re-construct the answer
What is a notch maneuver?
Notch maneuver is when an aircraft being tracked by a pulse Doppler radar (whether ground or air intercept radar from an adversary aircraft) flies perpendicular to the radar to escape detection and tracking. Since Doppler radars use Doppler shift to determine its target's velocity and whether it's flying away or inbound, when the targeted aircraft flies perpendicular relative to the radar, it loses it's Doppler shift, thus, the radar ignores it thinking that it's a stationary target such as mountains and etc.
What type of radar is able to take advantage of vary small changes in the frequency of the returned signal to give a more detailed radar image?
Doppler radar is sensitive to the changes in frequency of the returned signal caused by the movement of the "target" off which that signal is being reflected. Storm cells are moving concentrations of extremely humid air, and they reflect radar signals fairly well. By using a computer to analyze the small changes in the frequency of the returned signal (compared to the frequency of the transmitted signal - which we know), we can, by looking at this Doppler shift, paint a picture of the storm cell activity. A link is provided to the Wikipedia article on Doppler radar. You can get more detailed information there. The above is correct but is worth noting the following too: Doppler RADAR will be able to detect Doppler shift, but the fidelity to which they detectable or are know to is a function of the Pulse Repetition Ration (PRF) and the number of sample collected. So it depend what frequency you are looking and the fidelity you are looking for. Also note that Doppler is a function of the Carrier Frequency not the pulse modulation, and it should be noted that that some carrier frequencies are more susceptible to water and air molecule resonate then others. Finally the choice of wavelength and polarisation are fundamental to match what your are looking to see.
Is the Doppler radar the only satellite radar in the world?
Actually the Doppler Radar aka nexrad Next generation radar is not a satellite it is a radar. Satellites are floating around the world in space and Doppler radars are here on earth to monitor weather. As far as I know the Doppler radar is the only weather radar in the world. It is basically the only thing used for monitoring weather. I the above is not quite correct. Weather radars come in two basic types coherent and non-coherent. The Coherent radar come in Doppler Radar which can be FMCW or Active Pulse Doppler. The non coherent Pulse Radar merely aim high energy pulses at the clouds and display the returned power in a colour display. The coherent version integrates many pulses together to gain a Higher signal to Noise and to detect water drops moving in clouds. That aside, to answer the question which has nothing to do with weather radar, Doppler radar is frequency used in space verticals because its coherent processing gains in achieves help to offset the ranges it operates over, but it is not the only radar technique to be used on satellites and it depends on what the radar is trying achieve. Note that Doppler radar is non a synonymous exclusively of "nexrad Next generation radar".
What is the bowling speed for a 12 year old?
Doppler effect : we can measure the speed of ball Doppler principle .we transmit continuous pulse at ball at instant that echo reflect that change in trasmiting and receiving frequncy we can calculate the speed of ball.
