Abstract : An IFF active readout control and display system using majority logic and PPI position correlation techniques is being developed in the Data Processing Branch. Up to five target responses in each interrogated mode are stored, and majority-voting logic determines the confidence of the stored returns in each mode. So long as a gated target's interrogation responses are present during one scan, the numerical processing continually attempts to increase the confidence of the stored returns. The position correlation techniques point out the location of the responding target on the PPI. A true range and azimuth video gate technique, which can work with analog or digital PPI sweeps, has been devised. This video gate technique works in conjunction with the PPI retrace insertion method employed. (Author)
