In individual combat environments, our radar can be used for detection in complex environments. For example, in harsh environments with extremely low winter temperatures (below -40°C) and heavy snow cover, our radar system demonstrates exceptional low-temperature adaptability and reliability. The device operated continuously for over five months, withstanding extreme cold (minimum core component temperature of -45°C), persistent snow cover (snow depth up to 30 cm), and repeated freeze-thaw cycles (daily temperature fluctuations exceeding 20°C). During this period, its detection range, target tracking stability, and system startup response speed remained within design specifications, without any malfunctions such as electronic component failures, mechanical part jamming, or battery performance degradation due to low temperatures. This fully validates the product's ability to operate stably under ultra-low temperatures and heavy snow cover, providing new possibilities for individual combat operations in such environments.
