Range, or distance, is determined by measuring the total time it takes for the radar signal to make the round trip to the target and back (see below). The angular direction of a target is found from the direction in which the antenna points at the time the echo signal is received.
Read moreWhat is the radar range equation?
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 moreHow do you measure radar?
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 .
Read moreWhat is RMS in radar?
RMS-M. Microwave motion sensor with basic functionality. Reliable detection of people and vehicles. Simplest adjustement of the sensing range.
Read moreHow is radar range of resolution calculated?
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.
Read moreHow do you evaluate radar performance?
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 …
Read moreHow do you find the maximum unambiguous range?
The maximum range from which a transmitted radar, lidar, or sodar pulse can be reflected and received before the next pulse is transmitted. This range, rmax, is given by r max = cT/2 , where T is the interpulse period and c is the speed of light (or speed of sound in the case of sodar).25 Nis 2012
