The UAV-R22-1 obstacle avoidance radar utilizes Frequency Modulated Continuous Wave (FMCW) technology in the 77–81GHz band. Its 2T4R MIMO antenna configuration enables precise measurement of target distance, relative speed, and azimuth angle within a ±15° field of view. The integrated DSP+ARM dual-core architecture handles signal processing, target detection, and tracking algorithms on-chip, outputting processed data via UART.
Engineered for demanding applications, the sensor operates across an extended temperature range of -40°C to +85°C and is sealed to an IP67 standard for dust and water resistance. Its low power consumption and compact form factor make it ideal for integration into battery-powered autonomous systems requiring reliable environmental perception.
