<p>A radar apparatus is comprised of: receiving means for IQ-phase-detecting a reception electromagnetic wave received when a transmission electromagnetic wave is reflected from a target object and returned from the target object; signal converting means for FFT-processing an output signal of the receiving means; and amplitude level correcting means in which if there are one pair of spectrums having positive and negative peak values of amplitude levels, while absolute values of frequencies thereof are identical to each other, among the data converted by this signal converting means, then the amplitude level having the larger peak value is corrected so as to acquire a peak value of a true amplitude level. In the case that spectrums having both the positive and negative peak values and the frequencies whose absolute values are identical to each other are acquired as (Ab+jBb) and (As+jBs), the amplitude level correcting means calculates the peak value of the true amplitude level as {(Ab+As)2+(Bb-Bs)2}½.</p> |
