1. An ultrasonic diagnostic apparatus comprising:
transmitting and receiving circuitry configured to transmit and receive ultrasonic waves; and
processing circuitry, wherein
the transmitting and receiving circuitry is configured to
perform first beamforming processing on reflected wave signals output from a plurality of transducer elements configured to receive reflected waves, and
perform second beamforming processing different from the first beamforming processing on the reflected wave signals, and
the processing circuitry is configured to
calculate an evaluation value of spatial correlation of the reflected wave signals, and
perform third beamforming processing that combines a first processing result and a second processing result based on a combination ratio according to the evaluation value, the first processing result being a result of the first beamforming processing, the second processing result being a result of the second beamforming processing.
