Abstract

A system for characterizing a moving object performs a cluster trajectory orientation process associated wi th clusters of detected points in each of a set of scans to estimate the heading of a non-point target. The cluster txajectory orientation process performs a principal component analysis on a corresponding position data matrix representing coordinates of the clusters of points for each of aset of scans and compares resulting eigenvec tors to a heading of the cluster averages to generate a heading estimate. The heading estimate is combined with velocity estimates from a point target based tracking process and a Doppler-azinnith profile process in a weighted combination based on target attributes to improve the accuracy and performance of the system.

Description

technical field [0001] This disclosure relates to the field of object detection and tracking systems, and more particularly, to the field of radar and lidar processing systems and methods. Background technique [0002] For example, conventional object detection and tracking systems including high resolution radar devices and lidar devices are commonly implemented to track the position of objects in their field of view and estimate the velocity of detected objects. Such conventional object detection and tracking systems are typically configured to identify and track target objects based on a point object model that assumes that the system receives only one valid detection of a signal reflected from the target object. However, when a non-point object of some considerable size and / or elongated shape is within close range of a high-resolution radar or lidar device, the device may receive multiple valid reflections from different parts of the non-point object . [0003] The det...
