MONOLITHIC GAAS MIMIC EXOATMOSPHERIC JAMMER

A MINIATURE AND LIGHT-WEIGHT JAMMER SYSTEM UTILIZING ACOUSTIC CHARGE TRANSPORT (ACT) DEVICE AND OTHER GAAS CIRCUITS IS PROPOSED FOR A MONOLITHIC GAAS MIMIC IMPLEMENTATION. THE JAMMER WITH A MINIMUM BANDWIDTH OF 200 MHZ WILL PROVIDE WAVEFORM-SPECIFIC MULTIPLE JAMMING ECHOES WITH PROGRAMMABLE DELAYS AND DOPPLER SHIFTS FOR RANGE GATE PULL-OFF AND ANTI-MTI JAMMING. THE DESIGN AND IMPLEMENTATION OF THE KEY GAAS CIRCUITS ARE DISCUSSED. PHASE I PROGRAM WILL PROVIDE A DETAILED DESIGN OF THE JAMMER SYSTEM DOWN TO THE TRANSISTOR LEVEL TOGETHER WITH THE DESIGN OF THE ACT DEVICE, SYSTEM INTEGRATION, GAAS MIMIC FOUNDRY SELECTION, AND JAMMER PERFORMANCE ANALYSIS.
