Radio emission from extensive air showers

We review research on the currently topical high-energy physics problem of using the radio emission from extensive air showers to detect ultra-high-energy cosmic particles. We present experimental results on the shower radio emission and consider laboratory experiments on modeling radio emission from electron beams and high-energy gamma quanta. Also reviewed are current views on radio emission mechanisms from showers caused by high-energy particles in the meter and centimeter wavelength ranges. The use of the radar method to study air showers is discussed. The theoretical concepts of the emission of coherent and noncoherent radiation in the superhigh frequency range are briefly reviewed, and the possibility of reconstructing shower parameters from radio emission data is considered.
