  Detection techniques at radio wavelengths play an important role in the
future of astrophysics experiments. The radio detection of cosmic rays,
neutrinos, and photons has emerged as the technology of choice at the highest
energies. Cosmological surveys require the detection of radiation at mm
wavelengths at thresholds down to the fundamental noise limit. High energy
astroparticle and neutrino detectors use large volumes of a naturally occurring
suitable dielectric: the Earth's atmosphere and large volumes of cold ice as
available in polar regions. The detection technology for radio detection of
cosmic particles has matured in the past decade and is ready to move beyond
prototyping or midscale applications. Instrumentation for radio detection has
reached a maturity for science scale detectors. Radio detection provides
competitive results in terms of the measurement of energy and direction and in
particle identification when to compared to currently applied technologies for
high-energy neutrinos when deployed in ice and for ultra-high-energy cosmic
rays, neutrinos, and photons when deployed in the atmosphere. It has
significant advantages in terms of cost per detection station and ease of
deployment.
