Radar waves travel at the speed of light, approximately 300,000 km/second, so it would take 1/30,000 second for them to make the 10 km round trip.
Pulse rate is either set up by the operator or the equipment designer. Range of some detected object is determined by the speed of light and the distance of the object causing the return signal pulse, using the formula: distance= velocity of light multiplied by half the time delay for the return echo.
The radar signal travels at the speed of light, which is approximately 186,282 miles per second. Therefore, the time it takes for the signal to go to the airplane and return would be around 0.0015 seconds.
The goal of stealth technology is to make an airplane invisible to radar. There are two different ways to create invisibility:The airplane can be shaped so that any radar signals it reflects are reflected away from the radar equipment.The airplane can be covered in materials that absorb radar signals.
Electromagnetic waves are used by traffic controllers through radar systems to track and monitor airplane traffic. Radar works by emitting electromagnetic waves from an antenna that bounce off aircraft and are then detected when they return. This data is used to determine the position, speed, and direction of aircraft in real-time, assisting air traffic controllers in ensuring safe and efficient air traffic management.
Increasing the pulse repetition frequency can improve target detection and tracking capabilities. However, it can also increase the likelihood of signal clutter and decrease maximum unambiguous range in radar systems. Balancing these factors is crucial to optimizing radar performance.

Radar Pulse Repetition Frequency - The number of pulses the radar system sends out to the target. A pulse can contain multiple frequencies.
CW or continuous-wave radar cannot determine range due to the lack of a listening period where the radar signal is silent. Pulse radar has a silent listening period (hence the name pulse radar). Therefore it can determine the range of the object causing the return by counting the elapsed time between transmission and receipt of the echo. The above is not quite correct, Continuous Wave Radar and Pulsed Radar differ by there relationship between the Pulse Width (tau) and the scene size (Swath). CW Radar's determine range by Frequency Modulation (FM) ranging this means that they ramp the RF frequency within the pulse during the transmission and are known as FMCW Radar. Pulsed Radar on the other hand use the pulse timing but can also use the FM Ranging trick to enhanced there signal to noise and reduce there probability of interference or detection/interception. CW radar can deduce range by delaying the transmit signal and mixing it with the receive such that it becomes a homodyne receiver and in such cases it is usual to ramp the RF and perhaps use two aerials rather then just one with a duplexer switch like in a Pulse radar system. Edit- hmm i feel the above answer is bit too complex... i don't think typical person would go as far as concerning FM or Pulse Delay Ranging here's my Answer DIFFERENCES BETWEEN PULSE AND CW RADAR Basis -Transmission Pulse RADAR puts delay between transmitting and receiving periods so the time between transmitted pulse and received pulse is different While CW RADAR, Transmit continuously -Antennas Pulse RADAR may use same antenna for Receiving and Transmitting , when transmitting the receiver is "blanked" and while Receiving the receiver is Activated and transmitter is blanked .. this is done by a device called "Duplexer" CW RADAR typically used 2 Antennas, one for transmit another one to Receive since there are no delay to receive as what usually seen in pulse RADAR -Ranging technique Pulse RADAR may use "Pulse Delay Ranging" to provide Range measurements , Frequency Modulation Ranging may also possible , especially for pulse RADAR that transmit many pulses and have very shot time to "listen" example is FMICW (Frequency Modulated Interrupted Continuous Wave RADAR) While CW RADAR provides Range by means of Doppler based Ranging (FM Ranging)
Radar.
The leading edge of a radar pulse determines range accuracy. The trailing edge, along with pulse width, determines minimum range.
Reflectivity with radar is measured by sending out a pulse of microwave radiation and then analyzing the strength of the return signal. The strength of the return signal provides information on the amount of radiation reflected back to the radar unit, which can indicate the size, shape, and composition of the target. Reflectivity values are typically represented in units of decibels (dBZ) in meteorological radar applications.
airplane..bwahahahaha....

Secondary radar system are known as "Interrogator/Transponders" and are cooperative radar systems. The Interrogator transmits a pulse pattern that signals the kind of response they are looking for transponders that receive it. The transponder replies with a pulse pattern on a different frequency. Transponders can also carrier coded information that give more then just there position. Most typical transponder system is associated with Air Traffic Control Radar. Air Traffic Control systems integrate the primary radar return (non-cooperative return) with the position and coded data from the secondary radar (cooperative return) that will also provide flight information like Squawk code (a Unique ID) altitudes speed position etc. The maritime equivalent has three equivalents SART (Search and Rescue Transponder), Racon Buoys (Navigation transponders that respond to maritime radar pulse width) and a systems that is not really radar but is VHF transmission and is called AIS (Automatic Identification System) but perform similar information to the ATC system. However when the term Secondary Radar is used it almost always means ATC Interrogator Transponder system or the military version system.
Is turned off after each pulse.
No, it is done at the receiver.
