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

本项目是为射电天文学实验开发工作而开发的多通道低噪声接收机、数据采集和数字信号处理系统。该系统将支持正在进行的多项研究工作，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的开发工作，焦平面阵列和合成阵列的射频干扰缓解算法，以及用于验证和改进长波合成成像中方向相关自校准的电离层校正技术的数据收集。

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.
