Key Term 5

Core concept from section 5 of chapter 41.

Theorem: OMP Recovery Guarantee

OMP exactly recovers an ss-sparse signal from MM measurements if the mutual coherence μ\mu satisfies:

μ<12s1\mu < \frac{1}{2s-1}

This is a sufficient but not necessary condition.

Example: Matched Filter Reconstruction

Apply back-projection to a sparse scene and visualize sidelobes.
