A Study of the Effects of Noise Jamming on Radar Receivers

Abstract

A comprehensive study of the effects of noise jamming on various pulsed radar receiver types is proposed. First, a literature review on the sources of electrical noise and various jamming waveforms is presented. The power spectra for three noise jamming waveforms are rigorously derived. These cases are shot noise in a parallel-plate diode, a series of pulses with random amplitudes and intervals, and for a series of pulses with random amplitudes, spacing and phases. Next, the probability density functions for the output of linear and quadratic detectors are developed. For each detector type, the probability density functions for the cases of noise only and signal plus noise are derived. Finally, the effects of CW interference on conventional pulsed radar receivers is accomplished. This analysis shows that the effect of pure CW tone is detuned from the signal carrier frequency the minimum power required for detection increases until the detuning is so great that the effects of the CW is negligible. This thesis lays the ground work for a much broader future study of the effects of noise jamming on various pulsed radar receivers types. Theses.
