1. An ultrasound diagnostic apparatus, comprising:
processing circuitry configured to
execute transmit aperture synthesis to conduct coherent summation on multiple received signals that are at different transmit apertures and in an identical scan line,
evaluate a degree of consistency between phases of the received signals to calculate an evaluation value at each observation point such that the evaluation value increases as the degree of consistency between the phases increases, wherein the evaluation value is calculated for each of different frequency components included in the received signal of the multiple received signals, and
correct a received signal of the multiple received signals having undergone the transmit aperture synthesis based on the calculated evaluation value.
