Non-invasive geological survey is a technology of key importance for many areas of business and science – among others, for mining, construction or archeology. However, the current ground-penetrating radar (GPR) technology as well as other non-invasive geophysical methods have a number of very important limitations. The principle of operation of modern impulse radar systems is the emission of short, strong electromagnetic impulses of a given frequency, and the reception of reflections of these signals and their processing. This design has important practical drawbacks and limitations. First of all, the electromagnetic pulse must be very strong – even for a relatively shallow measurement, the power reaches several dozen kilowatts. Measurement in different frequencies requires mechanical interference in the device (exchange of antennas) and repeated measurements. The image of what is below the surface of the ground obtained in this way is very simplified and often insufficiently accurate to make important decisions with high degree of certainty. In addition, obtaining and interpreting such an inaccurate image still requires extensive expert knowledge.

Frequency modulated continuous wave radar developed by WIDMO Spectral Technologies  (formely  SGPR.TECH) will solve many of these problems and will facilitate the work of teams prospecting for mineral deposits, examining the ground for the construction of buildings, or dealing with the maintenance of embankments or landfills. The advantage of the broadband radar is the increased precision of the measurements. This enables the creation of a more extensive profile of the composition of subsurface structures, which will help to make important decisions with greater certainty. It will also shorten the measurement time considerably, which will allow for not only accurate but also quick mapping of an area. The use of new technology will drastically reduce the energy demand of the system. The use of an extremely wide frequency band, also including very low ranges, will allow measurements at much greater depths than those offered by pulse-based radars. The large amounts of detailed data collected by the GPR will be developed by dedicated software. It will make the interpretation of data much simpler, especially since the interpretation of the traditional impulse GPR data requires profound specialist knowledge.

The WIDMO Spectral Technologies team combines scientific and business experience. Professor Andrzej Kułak, doctor Cezary Worek and Jerzy Kubisz, employees of the Electronics Department of the AGH University of Science and Technology in Kraków and of the Astronomical Observatory of the Jagiellonian University are specialists in the field of propagation of radio waves, radioastronomy, microwave technology, electromagnetics and design of electronic equipment. Mirosław Trześniowski and Tomasz Trześniowski will be in charge of the business aspects of the venture. Their experience gained from PwC and KGHM will help to develop an effective business strategy. The company was founded in 2018.
