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.

d = Distance between the antennas. G (Tx) = The Gain of the Transmitting Antenna. G (Rx) = The Gain of the Receiving Antenna . The free space path loss is used to predict the strength of a RF signal at a particular distance.

In order to double the range, the transmitted power would have to be increased by 16-fold ! In order to double the range, the transmitted power would have to be increased by 16-fold!
Read moreWhat is pulse radar and continuous wave radar?
Pulse Radar is use for detecting of target location . and CW Radar stands for continuous wave radar. Here is difference between Pulsed RADAR and CW RADAR. Pulsed RADAR : In this system the pulse modulated signal are used for transmission.28 Oca 2011
Read moreWhat are the applications of CW radar?
A continuous wave (CW) radar has been used for the detection and classification of people based on the Doppler signatures they produce when walking . When humans walk, the motion of various components of the body including the torso, arms, and legs produce a very characteristic Doppler signature.
Read moreWhat is the principle of FM radar?
The radar principle used is FMCW (Frequency Modulated Continuous Wave) . The FMCW-radar transmits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). The signal is emitted, reflected from the measuring surface and received with a time delay, t.
Read moreWhy CW radar can measure range?
CW radar can measure the instantaneous rate-of-change in the target’s range. This is accomplished by a direct measurement of the Doppler shift of the returned signal . The Doppler shift is a change in the frequency of the electromagnetic wave caused by motion of the transmitter, target or both.
