Method for Realizing the Possibilities of the Dulkyn Low-Frequency Gravitational-Wave Detector

A system is proposed for self-compensating low-frequency noise in the Dulkyn pentagonal laser-interferometer low-frequency gravitational-wave detector. For a signal-to-noise ratio at the output of the optical part of the scheme of no better than 10–7, the system makes it possible to operate in real time after roughly 25 periods of a detected gravitational-wave signal. With the orbital motion of the Earth this will make it possible to implement an antenna (a response of the detector to gravitational radiation) having an artificial aperture and a radiation pattern width of a few minutes of arc.
