A simplified method for calculating the bounds on the emission spectra of chirp radars

Simple equations and procedures were developed that permit rapid hand-calculation and plotting of an approximation of strong bounds on the spectra of linear frequency modulated RF pulses that have a trapezoidal envelope. The approach used in deriving the model involved the use of an asymptotic expansion instead of the usual Fresnel integrals to describe the skirts of the voltage-density spectrum.
