Correlation is used to enhance the temporal resolution capability of incident energy detectors for high bandwidth signals. Such enhanced resolution is attained by using a primary response of the detectors, which may be weak but which accurately replicates the temporal waveshape of the incident energy pulse. A secondary response of the detectors, which is delayed from and more powerful than the primary response, but does not track the incident energy pulse as well as the primary, is correlated with the primary response. The secondary response is preferably passed through an inverse matched filter to provide a pulse more faithfully following the incident energy pulse prior to correlation with the primary response. Circuitry is provided for performing the enhancement, and a modulating device is used to permit the detector to respond to long-duration incident energy.
