摘要
使用普通商用毫米波FMCW雷达收发器对9 mm子弹模型进行校准RCS测量,在77~81 GHz频率范围内,通过测量纵横角的变化得到校准RCS值,并将实验结果与仿真结果进行比较,结果表明两者之间存在合理的匹配。证明了使用低成本商用雷达系统在77~81 GHz频段上测量RCS的方法是可行的。
The calibrated Radar Cross Section(RCS)of the 9 mm bullet model is measured by using a commercial low-cost millimeter wave frequency modulated continuous wave(FMCW)radar system in 77~81 GHz frequency range.The calibrated RCS can be obtained by measuring the variation aspect angle,and compared with the simulation results which shows fair matching between these two.The feasibility is proved that a commercial low-cost systems can be used in measuring RCS in 77~81 GHz frequency range.The study reveals that the low-size objects can be measured by low-coat radar systems.
