Combining signal images includes receiving signal images and performing the following to yield a weighted sum for at least one signal image. A phasor is generated from a signal image in accordance with a correlation reference, and a phase alignment of the signal image is adjusted to yield an adjusted signal image. A signal magnitude estimate is determined in accordance with the phasor, and a weight is determined in accordance with the signal magnitude estimate, where the weight reflects a signal-to-noise ratio of the signal image. The weight is applied to the adjusted signal image to yield a weighted sum for the signal image. The weighted sums are combined to yield a combined signal output.
