Abstract :
The authors describe a quad channels, high speed, large capacity storage, high resolution data acquisition system used in automatic millimetre-wave radar full polarization target recognition system (ATR). Millimetre-wave high resolution radar (HRR) target recognition is an interesting research area for fully polarized radar data acquisition. The system described achieves 20 mega sample per second conversion rate. The system includes six sections: quad channels high independent buffer amplifier, quad monolithic high resolution analog-to-digital converters, logic control circuit, data buffer memory, high transfer rate interface, and data acquisition software. High speed, high resolution and integral nonlinearity are the main technical features
