Abstract:

A technique called coherent overlaying was developed for improving the signal-to-noise ratio in plots of radar return vs. time. The essential feature of the technique is a phase corrected summation of pulses which have been scattered by the same point on a target. Several test cases are discussed and the time signature of ATS-3 which was too weak to be extracted by regular processing of Millstone Hill radar data is presented.
