New applications: Computer systems at work

Scientists at the National Severe Storms Laboratory (NSSL) in Norman, Oklahoma expect to be able to read the deadly signature of a tornado quickly on the display scope of a new radar processor. The processor, developed by Technology Service Corporation of Santa Monica, under a contract from Lockheed Electronics Company, Inc. uses the Fast Fourier Transform (FFT) algorithm to sample radar signals in real time and to produce their frequency spectra.
