Spurious Sidebands of a Linear Signal

For interference evaluation studies, the voltage or power spectrum of transmitting systems must be known. This paper evaluates the magnitude of the sideband power levels for linear FM carriers. Carriers of this type are encountered in FM-CW and FM pulsed radars. Analytical expressions are derived and spectral amplitudes are plotted which permit rapid evaluation of spurious sideband powers as a function of a normalized frequency deviation about the carrier.
