Receivers for Low-Frequency Radio Astronomy
The next generation of large telescopes for low-frequency radio astronomy will consist of tens of thousands of broadband antennas, each individually instrumented with receivers having large tuning range and instantaneous bandwidth. Because the number of receivers is very large, their cost must be minimized; however the receivers must be also be able to cope with the severe interference associat...

متن کاملAdaptive beamforming system for radio-frequency interference rejection
8MHzBP filter at -Q+ bandpass 70 MHz filter Abstract: Results from an experimental antenna array that is processed adaptively to cancel external radio-frequency interference are presented. The eight-element array has been tested in a far-field anechoic chamber. The adaptive beamformer rejects sidelobe and main-lobe interference by up to 37 dB. A conventional Fourier beamformer rejects interfere...
متن کاملRadio Frequency Interference
We describe the nature of the interference challenges facing radio astronomy in the next decade. These challenges will not be solved by regulation only, negotiation and mitigation will become vital. There is no silver bullet for mitigating against interference. A successful mitigation approach is most likely to be a hierarchical or progressive approach throughout the telescope and signal condit...
