In summary, pulsed radar offers several advantages over continuous radar. It is necessary for measuring distances, as it emits an EM pulse and measures the time between emission and reception. Pulsed radar also allows for high energy pulses with lower mean power output. On the other hand, continuous radar, such as CW radar, is better suited for measuring speed through the Doppler effect but is limited in its range and cannot measure distances.

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.

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.
 

1. What is the difference between pulsed radar and continuous radar?

Pulsed radar emits short bursts of radio waves while continuous radar emits a continuous stream of radio waves.

2. What are the advantages of using pulsed radar over continuous radar?

Pulsed radar has a higher range resolution, better target detection capabilities, and can operate at higher frequencies.

3. How does pulsed radar reduce interference compared to continuous radar?

Pulsed radar uses shorter bursts of radio waves, which reduces the amount of time that the radar is transmitting and therefore decreases the chances of interference from other signals.

4. Can pulsed radar be used for both short-range and long-range detection?

Yes, pulsed radar can be used for both short-range and long-range detection. The range of the radar is determined by the pulse repetition frequency and the duration of the pulses.

5. Are there any disadvantages of using pulsed radar over continuous radar?

One potential disadvantage of pulsed radar is that it requires more complex and expensive equipment to generate and process the pulses, compared to continuous radar.
