RADAR VIDEO DATA PROCESSOR.
Abstract
The report covers the design, fabrication, and acceptance testing of four solid-state Radar Video Data Processors (RVDP) intended for use as engineering models in the NAS Air Traffic Control Program. The RVDP accepts search radar video (Normal and MTI), antenna synchro voltages, and triggers from Airport Surveillance (ASR) or Air Route Surveillance (ARSR) radars; also accepted are beacon replies from ATCBI equipment. The function of the RVDP is to process these search and beacon inputs and furnish target messages to a Central Computer Complex (CCC). The RVDP detects targets statistically, determines target position to an accuracy of 1/16 NM in range and 0.088 degrees in azimuth, resolves targets which are at the same azimuth but separated in slant range by 1/4 NM (for ARSR) or 1/8 NM (for ASR), and resolves targets which are at the same range but separated in azimuth by 1.5 antenna beamwidths. Radar targets are detected by an advanced, double-threshold method which minimizes the quantizing of noise as target hits and reduces the number of false alarms due to clutter. A salient RVDP feature is the automatic clutter eliminator (ACE), which assures a high probability of detecting primary radar targets otherwise obscured by thermal noise or clutter.
