Pt = Transmit Power. fo = Transmit Frequency. Lamda = Transmit Wavelength. G = Antenna Gain. Sigma = Radar Cross Section .
Read moreWhat is radar loop gain?
In telecommunications, the term “loop gain” can refer to the total usable power gain of a carrier terminal or two-wire repeater . The maximum usable gain is determined by, and may not exceed, the losses in the closed path.
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 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 .
