Simulation optimizes noise jammer design
Abstract
Direct noise amplification (DINA) and pseudo noise (modulated carrier - MC) are the two techniques used to approximate white Gaussian radar jamming noise. DINA is seldom employed because of its inefficient demands on the microwave amplifier. MC features modulation of a carrier signal to induce a Gaussian waveform at the victim receiver. The MC method attains a high efficiency with a carcinotron power oscillator, provided the Gaussian noise quality (GNQ), which is a function of the modulating signal parameters, is good. Results from a mainframe computer simulation indicate that the jammer bandwidth needs to be at least as wide as the victim bandwidth. The GNQ decreases with nearness to the edge of the jamming band but is independent of the jamer bandwidth.
