The position of the video voltage in the domain of measured time following the transmitter pulse determines the distance of the target which reflected the energy . In radar, this time is called range.
Read moreWhat is the range in radar?
Range is the distance from the radar site to the target measured along the line of sight . The factor of two in the equation comes from the observation that the radar pulse must travel to the target and back before detection, or twice the range.
Read moreHow does radar detect distance and speed?
Police are now using a laser technique to measure the speed of cars. This technique is called lidar. It uses the same principles with light that radar uses with radio waves. Sonar, radar and lidar all use echo and Doppler shift to do the same things – they measure the distance and speed of objects by their reflections .
Read moreHow does a radar calculate range?
Standard Form of Radar Range Equation Therefore, we can say that the range of the target is said to be maximum range when the received echo signal is having the power equal to that of minimum detectable signal. We will get the following equation, by substituting R=RMax and Pr=Smin in Equation 6 .
Read moreWhat does reflectivity radar measure?
The Local Radar base reflectivity product is a display of echo intensity (reflectivity) measured in dBZ (decibels). “Reflectivity” is the amount of transmitted power returned to the radar receiver after hitting precipitation, compared to a reference power density at a distance of 1 meter from the radar antenna .
Read moreHow does radar measure distance?
The radar sensor measures distances, movements, and velocity. The sensor calculates the distance to an object by measuring the reflection of a high-frequency signal from that object . The transmitted signal is reflected by buildings, liquids, and so on.

In this example, the average power is 1 kilowatt. The average power, rather than the peak power, is the measure of the capability of a radar system. Radars have average powers from a few milliwatts to as much as one or more megawatts, depending on the application.
