Tracking System for Asynchronously Scanning Radars with New Correlation Techniques and an Adaptive Filter.
Abstract
An Automatic Detection and Integrated Tracking system (ADIT) is being developed at NRL using the video outputs of two asynchronously scanning search radars located in close proximity. The automatic detectors should provide good false-alarm regulation over a variety of environmental conditions. The tracking system uses an adaptive alpha-beta filter to develop a single track file from the detections from the two radars. The tracking system differs from previous single-radar tracking systems in the timing, filter update, correlation process, and track initiation as well as in the use of detections from two radars. The system has been operated against targets of opportunity at NRL's CBD facility and can maintain tracks on 50 to 60 targets in real time.
