The investigations into cosmic radio noise that I made with J. W. Phillips and S. J. Parsons arose from operational studies of the performance of radar equipment at about 5-m wavelength in 1944–45. To obtain greater detection ranges, preamplifier stages of low-noise factor were being tested, but they did not result in the expected improvement in radar performance. J. M. C. Scott, a theoretical physicist now at Cambridge, suggested to me that the limitation in effective noise factor might be attributable to cosmic noise, about which something was already known from the work of Jansky and Reber.
