摘要
针对FMCW(调频连续波)雷达回波的雷达散射截面滤波后存在的距离值突变超过阈值的问题,提出一种装船机溜筒防碰撞经滤波后的距离值线性回归拟合方法。该方法利用安置在装船机溜桶平台海侧、陆侧、南侧、北侧四面的八台ARS 408-21调频连续波雷达形成纵向与前向检测区域,在一个测量周期内采集目标距离与速度数据,借助雷达返回数据的各项状态位滤除非法回波,并引入线性回归拟合方法完成对突变超过阈值距离值的纠正。结论指出,与传统的采用微波雷达与编码器进行装船机溜筒防碰撞相比较,所提方法能在复杂工业场景以及多普勒模糊情况下,提高雷达分辨能力与测角精度,可抗杂波干扰、多径反射干扰及电子干扰等,通过雷达返回数据的各项状态位滤除掉非法回波,更为有效保护装船机溜筒及所在平台。
Aiming at the problem that the range value of FMCW radar echo exceeds the threshold value after the radar cross-section filtering,this paper completed the anti-collision fitting research of shiploader chute.In this paper,eight ARS 408-21 millimeter wave radars are used to form the longitudinal and forward detection areas.The target distance and velocity data are collected in a measurement cycle.The illegal echo is filtered by the status bits of the radar return data,and the mutation over the threshold distance value is corrected by linear regression fitting.It is concluded that,compared with the traditional anti-collision method of microwave radar and encoder,the anti-collision fitting method proposed in this paper can improve the radar resolution and angle measurement accuracy in the complex industrial scene and Doppler fuzzy situation,and can resist the clutter interference.It can filter out the illegal echo through the various status bits of the radar return data,which is more important It can effectively protect the chute of ship loader and its platform.
