Ground Penetrating Radar:
Direct and Inverse Problems

5 maja 2016, godz. 12:00

Plan prezentacji:

Starting from a brief overview of georadar development at IZMIRAN, we discuss main design characteristics of LOZA series of enhanced-power GPR, areas of application, and problem of processing subsurface probing data:

  • What GPR radiates (radiation pattern, EM pulse waveform);
  • What GPR sees (how soil parameters influence radar return pulse);
  • How can we reconstruct subsurface structure (coupled WKB approximation, 1D inverse problem, numerical examples);
  • Conclusion (what we are doing now).

Prelegent:

prof. Alexei V. Popov

Alexei V. Popov was born in 1940 in Krasnoyarsk, Siberia. In 1958 he entered the leading Russian technical university – Moscow Institute of Physics and Technology, from which he graduated in 1964 as scientist specialized in radio physics and acoustics. He received Candidate of Science degree (Ph.D. equivalent) in 1968 at the Acoustics Institute, Moscow, after postgraduate study in diffraction theory, supervised by Prof. G.D. Malyuzhinets. He was a member of Malyuzhinets’ research group pioneered numerical implementation of the “wave parabolic equation” technique in the middle 60ies.

From 1969 to 1973 A.V. Popov worked at the Computing Center of the Latvian State University (Riga). In 1973 he entered the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation (IZMIRAN) where he works now as the head of Radiowave Propagation Department. His Doctor of Science thesis defended in 1986 at IZMIRAN had the title: “Smooth perturbation method in the theory of wide nonuniform waveguides” and was aimed mainly at long-range radiowave propagation problems. His contribution to the development of electromagnetic theory was honored with the USSR State Prize in Science and Technology in 1990. He is internationally renowned expert in diffraction theory and numerical electromagnetics. His research group activity includes HF radiowave propagation, ionospheric radio sounding, ground penetrating radar.

From 1995 to 2012, A.V. Popov worked on a part-time basis at the Lebedev Physics Institute, developing simulation techniques and design approaches for X-ray zone plates and IR optical fibers. He belonged to the Moscow X-ray Optics Group maintaining prolonged collaboration with the Lawrence Berkeley National Laboratory, Center for X-ray Optics.

A.V. Popov lives in Troitsk, Moscow since 1973. He is married, his wife Marina is physicist too. They have two daughters (Anna – manager, Elena – artist painter) and eleven grandchildren. Hobbies: sports (yachting, tennis, cross-country ski), music, nature.
