Assessing the residual life and durability of structures in the construction industry is a major concern, not only in dangerous earthquake situations but also under normal conditions. Even if the building's structural systems have been inspected, additional periodic inspections are required to protect against corrosion hazards during the service life of the building. Employing non-destructive methods instead of destructive methods, such as stripping, offers a considerable advantage in terms of time and cost when analyzing the seismic performance of buildings, particularly when determining the number of reinforcements and corrosion in reinforced concrete structures. This preliminary study investigates corrosion detection using computer-based Frequency Modulated Continuous Wave (FMCW) RADAR, an alternative non-destructive testing (NDT) method being developed for use as part of decision support mechanisms in building inspections. For this purpose, initial measurements were carried out first. These included through-connection measurements, background measurements and perfectly conducting plate measurements. Measurements have been taken on both corroded and clean cylindrical metal materials to verify the corrosion detection capability of the instrument. The study was designed as 30 measurements, each with 200 data. The examination of the data sets obtained from FMCW radar revealed the presence of amplitude distortion and frequency shift in the response signals of the clean and corroded metal objects. Results show that corrosion on a metal object can be effectively detected by FMCW radar, which is being developed as an NDT device. Future case studies will be conducted to analyze and minimize the environmental impact of corrosion detection. The use of non-destructive methods, such as FMCW radar, can optimize time and cost while ensuring the safety and durability of structures in the construction industry.
