The maximum range of a radar system depends in large part on the average power of its transmitter and the physical size of its antenna .
Read moreWhat is the formula for radar?
Assume the target receives the incident power with an area σ, called the radar cross section (RCS), and radiates isotropically. Hence, the power density at the radar is given by: (10.5) Assume the radar antenna has an effective area Ae, which is related to the antenna gain by A e = G rλ 2/4π .
Read moreHow does radar determine range of a target?
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 moreWhat is meant by radar range?
Range is the distance from the radar site to the target measured along the line of sight . (3) 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 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 .
