AI Thread Summary
Pulsed radar offers significant advantages over continuous wave (CW) radar, particularly for distance measurement, as it emits electromagnetic pulses that reflect off targets, allowing for precise distance calculations based on the time delay of the received signal. The longer intervals between pulses enable pulsed radar to maintain high energy content while keeping average power output low, enhancing its range capabilities. In contrast, CW radars are primarily used for speed measurements via the Doppler effect but are limited to short ranges and cannot measure distances. The discussion also touches on the capabilities of Doppler lidar, which is effective for speed measurement but is considered short range, with 8 meters classified as limited in this context. Overall, pulsed radar is favored for applications requiring distance measurement, while CW radar and lidar serve specific speed measurement functions.

For what use? I would think that they would have adv./disadv. under different uses...
 
If you want to measure distances, you must use a pulsed radar. The device emits an EM pulse that goes to the target and is reflected. The radar receiver detects the reflected pulse and the information processing measures the time between emission and reception. This time is twice the distance divided by the speed of light.
Additionally, a pulsed radar has another advantage. The time between pulses is several order of magnitude greater than the pulse duration, so you can have a pulse with a high energy content (and longer range capability), while maintaining the mean power output relatively low.
CW radars are normally used for measuring speeds through the Doppler effect. They are short ranged and cannot measure distances.
 
lidar

It is a short range doppler lidar.
By the way, is 8m a short range in lidars?
 
Since it is a doppler device, it measures speed. And yes, 8 m is a short range.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
