ACT PROCESSORS FOR ECM APPLICATIONS

WITH INCREASING WAVEFORM COMPLEXITY AND EMITTER DENSITY IN THE TACTICAL ELECTROMAGNETIC SIGNAL ENVIRONMENT, THE JOB OF INTERCEPTING AND IDENTIFYING POTENTIALLY THREATS HAS OVERWHELMED THE CAPABILITIES OF CONVENTIONAL ESM RECEIVERS. THIS PROPOSAL DESCRIBES A PROGRAM TO STUDY THE APPLICATION OF ACOUSTIC CHARGE TRANSPORT (ACT) TECHNOLOGY TO ADVANCED ESM RECEIVER ARCHITECTURES. ACT IS AN EMERGING TECHNOLOGY WHICH ALLOWS PRECISION ANALOG TRANSVERSAL FILTERS TO BE INTEGRATED WITH AMPLIFIERS, DETECTORS, COMPARATORS, AND DIGITAL INTERFACE AND CONTROL CIRCUITS IN A SINGLE GAAS CHIP. THE MAIN FOCUS OF THE PROPOSED STUDY WILL BE TO DETERMINE THE EXTENT TO WHICH INTEGRATION OF THE RF FUNCTIONS FOR TWO SPECIFIC ESM RECEIVER ARCHITECTURES CAN BE ACHIEVED TO REALIZED THE BENEFITS OF MINIATURIZATION AND RELIABILITY WHILE MAINTAINING ACCEPTABLE PERFORMANCE AGAINST TYPICAL TACTICAL SIGNAL ENVIRONMENTS. THE ARCHITECTURE TO BE STUDIED ARE THE CHANNELIZED RECEIVER AND THE MICROSCAN RECEIVER.
