NAVAL DATA HANDLING SYSTEM CIRCUITS
Abstract
The Naval Data Handling System (NDHS) installed at the Naval Research Laboratory's Chesapeake Bay Annex is a 24-radar-target, rate-aided, analog tracking system. The NDHS has provisions for a detector, two trackers, and a monitor in the tracking part of the system. These four stations can insert, update, or change coordinate position data in the analog store. All stations, except that of the monitor, can compute and modify the velocity coordinates. Each station can control any of the 24 analog stores through the station store control panel. The monitor station can be switched so that this station becomes a display only station, while the store control is taken over by an external data link such as the AN/SSA-21. Rate-aiding is provided for all targets and is done automatically on all targets which have the velocity computation turned on. The rate-aiding is of the straight-line prediction type which is updated each time the radar antenna sweeps through the target azimuth. Velocity is computed automatically when the operator turns the velocity computer on and repositions the tracking marker in the usual ma ner. The velocity information is also refined during the normal tracking operation. (Author)
