Apparatus for detecting radar echo signals with a high degree of certainty in the presence of noise. A predetermined number of consecutive, constantly changing invervals are produced having a length equal to the radar pulse width. The resolution of the system is a function of the number of signal positions chosen for examination within each interval. A secondary signal is produced for each signal position and these secondary signals are summed over preselected resolution intervals. A weighting arrangement is provided which weights the individual secondary signals inversely with their distance from the central resolution interval of the set. |
