A system for detecting and tracking a multiplicity of targets averages radar video returns over small sectors for data smoothing and noise reduction, provides adaptive thresholding by determining noise levels in an area of interest and establishes a detection threshold in accordance with such noise level, stores the video data for reach target of interest so that multiple targets on the same bearing may be tracked, and reduces the probability of target swapping by adjusting the target window in accordance with target size and weighting the cells within the window.

The present invention is an apparatus for reducing distortion at the beginning of a line drawn on the face of a CRT. The line is started while the CRT intensity remains blanked. As the line reaches the position on the CRT where it is to be visible, the CRT intensity is enabled.
