The present invention relates to a two-dimensional radar video converter provided with an adaptive video processor using, in series, azimuth integration, mean level detection, and batch/batch correlation for target detection. The radar video converter also includes a computer interface module which selects from a plurality of threshold levels the signal thresholds to be exceeded in detecting targets in a particular radar environment. Together, the adaptive video processor and the computer interface module convert raw radar video into useful data which can be entered into a computer or used to display target detections at a convenient output.

A radar video converter for interfacing a two-dimension sweeping radar and a digital computer, comprising: an adaptive video processor which comprises: an azimuth integration stage, having video returns in digital form as inputs, for summing the video returns at each of a plurality of azimuths, the sum for each azimuth being taken over a plurality of ranges, and for providing an output corresponding to the sum of video returns at each respective azimuth, a mean level detector stage for receiving the output from the azimuth integration stage and for suggesting the presence of a target at a given azimuth when a target cell signal corresponding to the video return at the given azimuth at a given time exceeds a background threshold derived from signals at neighboring azimuths combined in a predetermined fashion, a batch/batch correlation stage for determining target detection correlation between successive sums of video returns summed at a given range on subsequent sweeps, means for providing a plurality of fixed threshold levels, means for separately comparing the fixed threshold levels with the target cell signal of the mean level detector stage, and threshold selection multiplexer means for selecting the mean level detector output or one of the fixed threshold comparing means outputs for use in determining a target detection output.
