A transmission method is performed by a transmitter including antenna elements. The transmission method includes: generating a digital calibration signal; performing digital-to-analog conversion on second digital signals to generate first analog signals, the second digital signals being obtained by adding the digital calibration signal to each of a plurality of first digital signals each corresponding to respective one of the antenna elements; performing analog-to-digital conversion on the first analog signals to generate third digital signals each corresponding to respective one of the antenna elements, the first analog signals each passing through respective one of the antenna elements; performing correlation calculation between the digital calibration signal and each of the third digital signals to calculate transmission delay characteristics each corresponding to respective one of the antenna elements; calculating transmission delay correction amounts based on the transmission delay characteristics; and correcting the transmission delay characteristics based on the transmission delay correction amounts.
