The Canadian Hydrogen Observatory and Radio transient Detector (CHORD) is a new radio telescope facility, incorporating the latest advances in dish fabrication, low-noise electronics, and digital signal processing. Using bandwidth × field of view × sensitivity as a figure of merit, CHORD will be an order of magnitude more powerful than its predecessor CHIME, and be the world-leading facility of its type.
Large and precise collecting area is made possible by composite technology pioneered at Canada's National Research Council (NRC). CHORD will feature 512 × 6m dishes in a central array, with 64-dish outrigger arrays at two remote sites.
Custom designed receivers matched to ambient temperature, ultra-low-noise amplifiers will deliver <30 K system temperature across a 5:1 bandwidth (300-1500 MHz).
