Asymptotic Behavior of the Spcetra of RF Pulses with Linear Frequency Modulation

Abstract

The asymptotic spectra of wide-band radio frequency pulses with linear frequency modulation are evaluated. It is specifically shown that at frequencies (measured from the carrier frequency) much larger than the maximum FM deviation the effect of the FM is small. In particular, at a frequency 50 mc higher than the carrier frequency, the envelope of the spectrum of a 10 microsecond rectangular pulse with a 10 mc FM deviation is less than 1% above the envelope of the spectrum of a pulse with no FM. The spectrum of a cosine pulse with these same characteristics is increased by less than 3%.
