Abstract

A method of imaging a moving object, including the steps of acquiring radar data reflected by the moving object, determining a motion state of the moving object; and generating a three-dimensional representation of the moving object based on the determined motion state, is disclosed. The motion state may be a complete solution of translational and rotational motion determined based on at least one of the inertia tensor components of the moving object, or solutions of Euler'"'"'s torque-free equations of motions. The three-dimensional representation may be generated by reconstructing static patterns of the moving object based on estimated initial translational and rotational conditions of the object. A system for imaging the moving object according to this method is also disclosed.

Claims

1. A system for imaging a moving object, the system comprising:

a receiver configured to acquire radar data reflected by the moving object;

a memory configured to store instructions for processing the acquired radar data;

a processor configured to determine a motion state of the moving object and generate a three-dimensional representation of the moving object; and

a display unit configured to display the three-dimensional representation of the moving object based on the determined motion state.
