Techniques are discussed herein for analyzing radar data to determine that radar noise from one or more target detections potentially hides additional objects in the vicinity of the target detections. A determination may be made as to whether an object may be hidden based at least in part on a radar noise level based on target detection and a distribution of radar cross-section and/or Doppler data associated with a particular object type. For a location in the vicinity of the target detection, the radar system may determine an estimated noise level and compare the estimated noise level to a radar cross-section probability associated with an object type to determine a likelihood that an object of the object type is hidden at the location. Based on the analysis, the system may determine a vehicle trajectory or may control the vehicle based on a likelihood that the object may be hidden at the location.
本文讨论了用于分析雷达数据以确定来自一个或多个目标检测的雷达噪声潜在地隐藏目标检测附近的附加对象的技术。可以至少部分地根据基于目标检测的雷达噪声水平以及与特定对象类型相关联的雷达截面和/或多普勒数据的分布,确定对象是否可以被隐藏。对于目标检测附近的位置,雷达系统可以确定估计的噪声水平,并将估计的噪声水平与对象类型所关联的雷达截面概率进行比较,以确定该对象类型的对象在该位置被隐藏的可能性。基于分析,系统基于对象可能在该位置被隐藏的可能性,可以确定车辆轨迹或者可以控制车辆。
