What is it about?

Two-dimensional receive arrays can be used to measure twodimensional spatial coherence, but there is no well accepted measure of the coherence length in two dimensions. This paper proposes a metric that may be applied to these types of measurements.

Why is it important?

This metric gives a quantitative way to describe the spatial coherence of scattered fields which has not been discussed to date. This type of metric may be used to link spatial coherence to the underlying sediment properties or it may be applied to the modeling of the performance of different types of sonar systems such as Correlation Velocity Logs or Synthetic Aperture Sonars.

Perspectives

This article was enjoyable because it is the first (but hopefully not last) paper to come from my dissertation. The spatial coherence of scattered fields in an interesting topic and I believe there is quite a bit of useful information contained in these two-dimensional measurements.
