Research on Unmanned Airborne Millimeter - wave Broadband Obstacle Avoidance Radar System Based on FPGA

摘要

UAVs often need to perform tasks in low-level complex environments. In order to protect the safety of UAVs, it is necessary to avoid radar and to avoid early warning and obstruction. In this paper, the obstacle avoidance radar of UAV is analyzed deeply, and a stable, low cost and miniaturized LFM broadband millimeter wave obstacle avoidance radar is designed to solve the problem of UAV flight safety. The test data show that the designed millimeter wave obstacle avoidance radar system meets the requirements of UAV obstacle avoidance.
