In ground penetrating radar, there are many number of reflected signals received by a receiving antenna. My doubt is, how these reflected signals are analyzed to estimate ground objects size, shape, position and what kind of 3-D display is used?

Dear Anvesh Kumar
GPR works on various frequency depending on the application for example it uses High frequency to measure shallow depth and small target and are ideal for concrete whereas Low frequency are typically used for the measurement of Deeper depth, larger target archaeological applications.
In case of the EM signals from various source such as cell tower, radio etc. this signals actually does not the actual damage the result of GPR but it interfere with the signal, producing noise in the result and making the data difficult to analyse.
moreover the transmitting and receiving antenna of the GPR operates on certain central frequency, other EM signals which doesn't include in the working frequency doesn't affect the GPR reading. we can view the whole scenario similar to the working of SONAR the only difference is sonar propagate sound wave and GPR propagate EM waves, there are lots of other sound noise in the water but sonar have its particular operating pitch of sound. likewise GPR have its operating central frequency.
I have attached a linked which gives about the details analysis of the display of the GPR you can check it out.
With warm regards

Look at the software Reflex developed by Sandmeier (and his website), you will find all the answers over there.
