(a) Dataset # 1 consisted of the responses from single scatterers. (b) One half of dataset #2 consisted of responses from a single scatterer (similar to dataset #1) and the second half consisted of the combined responses from two scatterers at different locations. (c) One third of dataset #3 consisted of responses from a single scatterer (similar to dataset #1), the second third consisted of the combined responses from two scatterers at different locations (similar to dataset #2), and the final third consisted of the combined responses from scatterers at three different locations.
