Ground radar is a technology that uses radio waves to detect objects beneath the Earth's surface. It sends out signals that bounce back when they hit different materials, allowing users to create images of what lies underground. This method is commonly used in fields like archaeology, geology, and construction to locate buried structures or assess soil conditions. The data collected by ground radar can reveal various features, such as pipes, cables, or ancient artifacts. By analyzing these images, professionals can make informed decisions without the need for extensive digging, making it a valuable tool for non-invasive exploration.
