1. An ultrasonic diagnostic apparatus, comprising:
processing circuitry configured to:
extract a third-or higher-order odd harmonic component from a reflected wave signal received by each element of an ultrasonic probe;
determine whether the reflected wave signal is saturated or not using the extracted third-or higher-order odd harmonic component;
multiply the reflected wave signal of an element for which the reflected wave signal is determined to be saturated by a weight coefficient to decrease a contribution of the reflected wave signal of the element; and
generate reflected wave data by performing phasing addition on the reflected wave signal multiplied by the weight coefficient.
