OMP-Based Translational Motion Estimation for a Rotating Target by Narrowband Radar

What is it about?

Using wideband signals for translational motion compensation (TMC) is well known, thanks to the existence of many range bins. For narrowband radars, one may have only a single range bin. TMC processing must rely on the target's rotational motion in the slow-time domain. This paper shows that orthogonal matching pursuit (OMP) - a well-known technique in compressive sensing - is very useful for this application.

Why is it important?

It's a simple yet efficient technique, and quite few alternative techniques exist for narrowband radars.
