Claim 19:
20. The non-transitory computer-readable medium according to claim 18, wherein the one or more signal waveforms comprise two signal waveforms, the correlation value is a cross-correlation value between the two signal waveforms, the signal received by the acoustic array is a pulse signal modulated by Linear Frequency Modulation (LFM), and
wherein the program when executed by the processor causes the processor to execute the processing further comprising:
calculating a Doppler coefficient, based on a peak value Rμμ(0) of an autocorrelation Rμμ(τ) of the cross-correlation value, a peak value Raa(0) of an autocorrelation Raa(τ) of the autocorrelation Rμμ(τ), and an absolute value of a frequency change rate and a pulse length to derive the target velocity.
