MRI: Development of a Flexible Multichannel Digital Receiver for Radio Astronomy

本项目为射电天文学实验发展工作之多通道低噪音接收器、资料采集及数位讯号处理系统之发展。该系统将支持多个正在进行的研究工作，以研究涉及天线阵列仪器和信号处理算法的新技术。应用包括厘米波段焦平面阵列开发工作，焦平面阵列和合成阵列的射频干扰缓解算法，以及验证和改进电离层校正技术的数据收集，用于长波合成成像中依赖方向的自校准。

This project is for the development of a multichannel low noise receiver, data acquisition, and digital signal processing system for experimental development work in radio astronomy. The system will support multiple ongoing research efforts to study new techniques involving antenna array instrumentation and signal processing algorithms. Applications include centimeter-band focal plane array development work, radio frequency interference mitigation algorithms for focal plane arrays and synthesis arrays, and data gathering to verify and refine ionospheric correction techniques for direction-dependent self calibration in long wavelength synthesis imaging.
