I doubt it. This sounds more like a potential military application (radar) in the testing or experimental phase, since (in the article's abstract) they invoke stealth and worry about radiating plasma noise, usually not a problem with a passive antenna in a non-hostile environment.
The bandwidth looks like it's in an appropriate region, too, but they are designing active radiators
/receivers, whereas a telescope has no reason to radiate
unless it is trying to "light up" a target - hardly likely outside our solar system, and generally impractical beyond the few closer planets and moons since everything else is so far away, and it's hard to have sufficient gain to light up something the size of even Jupiter at that distance, and not waste a lot of energy. Arecibo can light up the Moon or Venus, and that's about it. It illuminates the occasional asteroid, too, but the resolution is so poor that it is best used for doppler estimates of rotation rates and orbital parameter estimates, not surface imagery.
The interesting thing about signal reception in telescopy (?) is that you want to get as high a signal-to-noise ratio as possible, just to detect a signal that has been spreading for thousands to billions of years. With small optical telescopes, the greater the aperture, the more photons/s can be directed, properly focused, onto the detector. With larger telescopes, greater effective aperture can be obtained by spacing the scopes out in long baseline arrays, and using such aperture synthesis and Very Long Baseline Interferometry to mathematically reconstruct the signal and create images.
Currently in radio astronomy we use the Earth's diameter to get as wide a (real-time) terrestrial baseline as practical, although several European and U.S. and Australian radio telescope systems utilize smaller baselines very effectively, too. (For geometrical parallax to measure distances across space, where time is not crucial as it is in interferometry, we use the diameter of Earth's orbit as a baseline.) In the future there are plans to station orbiting telescopes a much wider distance apart and use micro-thrusters to maintain their distance apart as constant as possible during an observation. In radio telescopes, size matters, both dish aperture and baseline.
