Abstract:

SONOELECTRONICS PROGRAM LOW-POWER, HIGH-RESOLUTION 3D SONAR IMAGING SYSTEM. OBJECTIVE - DEVELOP HIGH-RESOLUTION, LOW-POWER LOW-COST, HAND-HELD SONAR IMAGER BASED ON SPARSE ARRAY CONCEPT - 128 X 128 PIXEL IMAGE 400 2D FRAMESs or 4 3D rendered FRAMESs WITH 1 cm CROSS-RANGE DOWN-RANGE RESOLUTION - FULLY-INTEGRATED ELECTRONIC BEAMFORMING. APPROACH - STATE-OF-THE-ART 2D SPARSE ARRAY TETRAD - BANDWIDTH SELECTION IMPROVING SIGNAL TO SIDELOBE RATIO NUWC - LOW-POWER, HIGH-THROUGHPUT CHARGE-DOMAIN ELECTRONIC BEAMSTEERINGBEAMFORMING TERATECH - ICs MANUFACTURABLE IN CMOS FOUNDRY TERATECH. ACHIEVEMENTS - WIDEBAND SPARSE ARRAY SIMULATION with 40 dB SIGNAL-TO-SIDELOBE RATIO -PROCESSING AND COMPONENT DEVELOPMENT 32-CHANNEL 1D TIME-DOMAIN BEAMFORMING 5 BILLION OPss 1 WATT. MILESTONES - SPARSE ARRAY WITH 32 ACTIVE ELEMENTS 799 - SPARSE ARRAY WITH 128 ACTIVE ELEMENTS - 128-ELEMENT SUBARRAY MODULE DEMO - 20X20 cm 2D SPARSE ARRAY WITH ELECTRONIC BEAMFORMING - 20X20 cm 2D SPARSE ARRAY WITH ELECTRONICS SYSTEM DEMONSTRATION.
