Abstract

A radar signal processing unit comprises a Fourier transform sectionfor executing Fourier transform of the received signal to a frequency signal, a frequency domain power calculation sectionfor calculating a power spectrum of electric power for each frequency from the frequency signal, an abnormal echo removal sectionfor determining the abnormal echo based on the power value of the power spectrum and outputting only the power spectrum not corresponding to the abnormal echo, an incoherent processing sectionfor performing incoherent integration of only the power spectrum not corresponding to the abnormal echo and averaging, and a signal detection sectionfor calculating the physical quantity of the atmosphere from the incoherent-integrated power spectrum.
