车载雷达不落地模式快速标校方法

A Fast Calibration Method for Vehicle-mounted Radars in Off-Ground Mode

车载精密跟踪测量雷达在野外执行任务时,常常不具备进行常规标校的条件,一套快速有效的应急标校方法,对于车载雷达不落地测量模式就显得尤为重要。本文以车载雷达不落地工作模式为例,介绍了车载雷达不落地工作模式的零值误差和轴系误差的快速标校方法。经工程实例验证,该方法实用有效,大幅缩短了雷达标校时间,提高了车载雷达系统的机动性。

A fast and effective emergency calibration method is particularly important for vehicle-mounted precision tracking and measurement radars operating in the off-ground mode in field scenario because the necessary conditions for normal calibration usually cannot be met in such a scenario.In this paper,a fast calibration method is proposed to reduce the zero-value error and axis system error of vehicle-mounted radars operating in the off-ground mode.Engineering test results show that the proposed method is practical and effective,which dramatically shortens the calibration time and improves the maneuverability of the vehicle-mounted radar system.
