  1. thanks! I would like to start by presenting our technology of work. Start over. I will be oversimplifying complex things so that ordinary readers (not engineers with higher education) can understand "how it works". There are radars on the market that work according to a primitive method: sending a signal and receiving a reflection. This method is described in most "scientific manuals". As a result of this work, the simplest radarograms are obtained. For example, you see such pictures on echo sounders that see fish: As you can see, each fish is seen as a small hyperbola (math curve). The more hyperbole, the bigger the fish. But what if we don't have fish underground? 🙂 If what we are looking for does not give a clear response-reflection? This is where an unusual theory comes to our rescue, which is called "Spiral Wave Geometry" (SVG). I will not overload you with mathematics, I will explain it simply. The main postulate of the theory: "Everything is a wave." Any micro or macro object interacts with the World at certain frequencies. Let's say you have a closet with opaque doors at home. You do not know what is inside it. Maybe there are dishes for guests? maybe there are glass glasses? How to find out ? You walk up to the closet and hit it with a sharp, quick blow. The entire contents of the cabinet are hit and begin to ring (make sounds). Every plate, every glass, every shelf is making sounds. The human ear receives these sounds, and the human brain decodes them. You can tell for sure after hitting: there are dishes in this cabinet! And it stands on the top shelf, and on the shelf in the middle there is glass, and at the bottom of the cabinet there are iron pans. What changed ? The approach to understanding has changed. I could take an ultrasonic emitter in my hand and separately receive a response-reflection from each part of the plate, from each pan. I would be able to see the reflection of the signal, but I will never understand from the reflection what exactly was the reflection? glass? metal? Spiral Wave Geometry gives us mathematical methods for processing the signal of reflected and excited vibrations from various objects in the earth below us. Our Ukrainian engineers decided to use the SVG for the operation of the GPR. This required a lot of mathematical processing, a lot of experiments on real objects. Ukrainian engineers do not receive $ 250,000 a year like Silicon Valley engineers 🙂 we do not have such salaries in Ukraine ... But this does not mean at all that our engineers do not have encyclopedic knowledge and thirty years of experience in radio and radio electronics 🙂 Equipment for georadar surveying in the world costs a lot of money, and software costs hundreds of thousands of dollars. This makes it inaccessible to ordinary people. Starting work on our radar, we wanted to make a tool accessible to an ordinary person, which would allow working with a GPR as with a conventional metal detector, i.e. visualize very complex signals in a simple and accessible way. We did it. And we managed to create an inexpensive solution.
  2. Greetings to all! My name is Alexander, I am from Ukraine (Eastern Europe). I represent myself and my friends, we developed a portable type GPR many years ago and gave it the name EasyRad. We have developed a georadar and software for it. We would like to get in touch (get contact) with those people or organizations who need to search for gold in the United States and Alaska. To my regret, on forums of gold prospectors and forums of archaeologists there are no sections "georadars", there are only metal detectors. I would like to convey to the searchers the information that GPR is not expensive and it allows you to explore underground spaces quickly and with great interest 🙂 We produce this GPR equipment, so we can answer all your questions. Our radar has a very affordable price for individual use, unlike other radars. See the web link below for examples. EasyRad GPR is a portable multi-purpose scanning ground penetrating radar of sub-surface probing for the problems of engineering geology, hydrogeology, archeology, ecology, field engineering as well as for search and rescue operations. https://www.easyrad.com.ua/index.php?r=index_en
