A mining company needs to understand what is happening underground. A sanitation utility may need to investigate interferences near its networks. In infrastructure, ground movement can pose risks to critical assets. In agriculture and forestry, soil moisture, biomass, and vegetation structure directly influence planning and productivity.

The challenges vary, but they share a common need: obtaining reliable data across large areas, including locations where conventional surveys may be difficult, time-consuming, or insufficiently representative.

Synthetic Aperture Radar (SAR) is one of the technologies used to address these challenges. Mounted on drones, it can generate physical data about the territory and support analyses of the surface, vegetation, and subsurface.

This range of capabilities explains why the same technology can support such different operations.

What Can SAR Radar Analyze?

SAR emits electromagnetic waves and analyzes the signals that return after interacting with the environment.

The result of the operation is not an aerial photograph. The collected signals are processed and transformed into data and maps that enable the analysis of physical characteristics across the monitored area.

Depending on the application and system configuration, radar can support analyses related to:

• Ground deformation, important for infrastructure, mining, and risk management;
• Subsurface conditions and buried structures, used in geotechnical studies, sanitation, mining, and research;
• Biomass and vegetation structure, relevant to agriculture, forestry, and environmental monitoring;
• Soil moisture, which can support agricultural management, water planning, and environmental studies;
• Large or difficult-to-access areas, where field surveys may require significant time, personnel, or physical intervention.

The ability to work with different types of information expands the range of technical challenges that can be investigated using the same technological foundation.

Infrastructure and Mining: Data to Anticipate Risks

In infrastructure and mining, some of the most important information for technical decision-making is related to the physical behavior of the terrain.

Deformations, displacements, instabilities, and subsurface characteristics can affect the safety of dams, slopes, civil works, and other critical assets.

SAR monitoring makes it possible to track these variables and generate information that helps engineers identify areas requiring further investigation or intervention.

This helps companies target inspections, prioritize resources, and make preventive decisions based on a more consistent technical foundation.

Sanitation: Investigating What Happens Around Underground Networks

For sanitation companies, access to subsurface information can mean less uncertainty before an intervention.

Radar can support the investigation of underground interferences, terrain conditions, moisture variations, and other factors that may affect water and sewage networks.

In expansion projects, maintenance operations, or problem investigations, this data helps technical teams better understand an area before deciding where to concentrate resources and complementary surveys.

This is especially relevant for extensive networks, where investigating an entire area exclusively through local methods can consume considerable time and budget.

Agriculture and Forestry: Understanding Soil and Vegetation at Scale

In agriculture and forestry, the challenge is different. The need is to understand how soil and vegetation characteristics vary across an area.

SAR can generate information related to soil moisture, biomass, and vegetation structure, making it possible to analyze spatial variations that isolated samples may fail to represent.

This data can support management decisions, water planning, forest inventories, crop monitoring, and the management of productive areas.

For large-scale operations, the density and distribution of information can make a significant difference in the quality of the analysis.

Why Can the RD350 Support Such Different Applications?

The RD350, developed by Radaz, is a multiband SAR system mounted on Class 3 drones.

Its architecture enables the use of different radar frequencies and, consequently, the investigation of different characteristics of the territory. This capability allows the technology to address challenges involving the surface, vegetation, and subsurface.

In addition, both the hardware and software are developed by Radaz in Brazil. This makes it possible to work with established applications while also investigating new demands presented by companies, universities, and research institutions.

Today, its applications extend across sectors including agriculture, forestry, mining, infrastructure, sanitation, environmental monitoring, land management, security, and research and development.

Which Challenge in Your Operation Still Depends on Insufficient Data?

This may be the most important question when evaluating whether a technology such as SAR makes sense for a company.

The challenge could involve characterizing the subsurface before construction, monitoring a risk area, understanding an underground interference, measuring moisture across a large area, or tracking vegetation characteristics.

The technical problem is the starting point.

If your company operates in infrastructure, mining, sanitation, agriculture, forestry, environmental monitoring, security, or research, contact Radaz and tell us about your operational challenge.

Our team can assess which data SAR can generate for your specific context and how it can support decisions with greater precision, predictability, and operational efficiency.
