Development of Color Displays

Notes:
Larry Hennington played a major role in developing NSSLís color displays. Here he is with Don Burgess in front to the Ling Computer. In 1973 the decision was made to develop the autocovariance estimator (i.e., the pulse pair processor that uses both amplitude and phase information to calculate the Doppler shift). This PPP was again designed and built by Dale Sirmans and his technician Glen Anderson and served NSSL for many years.
