The main objective of the CRC in High-Sensitivity Radiometers and Receivers research program is the development of novel receivers and beamforming methods to improve the sensitivity of antenna arrays for radio-astronomy and commercial applications. The goal of this program is to develop such systems by focusing on multi-dimensional beamformers and multi-port receivers. These will result in more sophisticated beamforming transfer functions, thereby enabling additional degrees of freedom in terms of beam bandwidth, orientation, and pattern. Multi-port receivers will make use of the spectral sparsity of incoming signals to isolate desired signals from noise and distortions associated with the array electronics.

CRC在高灵敏度辐射计和接收器研究计划中的主要目标是开发新型接收器和波束形成方法，以提高射电天文学和商业应用天线阵列的灵敏度。该计划的目标是通过专注于多维波束形成器和多端口接收器来开发此类系统。这些将导致更复杂的波束成形传递函数，从而在波束带宽、方向和图案方面实现额外的自由度。多端口接收器将利用输入信号的频谱稀疏性来将期望信号与与阵列电子设备相关联的噪声和失真隔离。
