    2626At the most raw level, radars generate time series of I (in-phase) and Q (quadrature) signals. These two signal components are considered to comprise a complex number.
    2727
    28 Additionally, the spectra of radar signals are stored as complex numbers.
     28Additionally, the spectra and covariances of radar signals are stored as complex numbers.
    2929
    3030Because of the very large dynamic range of radar signals (up to 10 orders of magnitude), these complex numbers are often stored as power, in log units, and phase, in degrees.
