AbstractFor target imaging and tracking systems, a key signal processing task is motion estimation. Specifically, the trajectory of a maneuvering target undergoing rigid body motion can be described through a series of translational and rotational transformations. Estimation of these motion parameters provides the tracking system enough information to calculate the targets trajectory over time. Determining the rotational motion to a high accuracy is also very important, as the imaging system can then form an image of the target over multiple aspect angles and thus increase the resolution performance. This paper focuses on algorithm development and performance limitations for motion estimation and image formation using active sensing arrays.
