Ground-penetrating radar (GPR) is a geophysical method that employs an electromagnetic technique The method transmits and receives radio waves to probe the subsurface One of the earliest successful applications was measuring ice thickness on polar ice sheets in 1960s (Knödel et al 2007)

What does GPR stand for?
Ground Penetrating Radar (GPR) The advent of Ground Penetrating Radar (GPR) can be traced back to as early as 1910 when the first patent for this technology was filed.
What is ground penetrating radar (GPR)?
The advent of Ground Penetrating Radar (GPR) can be traced back to as early as 1910 when the first patent for this technology was filed. After years of development in radio technologies, digital signal processing (DSP) as well as breakthroughs in the software field, GPR has become a highly valuable tool for many varied applications.
What are the different types of GPR systems?
GPR systems can be classified by the domain in which they work and bythe type of modulation. The first family of GPR systems is the time domain GPR. The principle of a timedomain GPR is to send a pulse at a given pulse repetition frequency (PRF) into theground and then listen to the backscattered echoes.
What is a time domain GPR?
The principle of a timedomain GPR is to send a pulse at a given pulse repetition frequency (PRF) into theground and then listen to the backscattered echoes. In the time domain GPR there aretwo major categories: the amplitude modulated and the carrier free GPR. The first onesends a pulse with a carrier frequency.
