Range accuracy

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.

RMS-M. Microwave motion sensor with basic functionality. Reliable detection of people and vehicles. Simplest adjustement of the sensing range.

Range resolution as a distance can be calculated as follows: R res = c * τ /2 Where, τ is the transmitted pulse width and c is the velocity of light in the free space. Narrower beamwidth is very useful to distinguish two adjacent targets.

When measuring the radio characteristics of a radar transmitter, the transmission power is measured with a power meter/sensor, the transmission frequency and frequency deviation are measured with a frequency counter, and the pulse duration transitions are measured with an oscilloscope .

The performance of a radar system can be judged by the following: (1) the maximum range at which it can see a target of a specified size, (2) the accuracy of its measurement of target location in range and angle, (3) its ability to distinguish one target from another, (4) its ability to detect the desired target echo …
