Basic System Concept for Integrating a 2D and a 3D Radar and Designs of Automatic Detection Systems.

摘要

A basic system concept of digitally integrating any 2D radar and any frequency-scan 3D radar was applied to the SPS-12and SPS-39radars,giving a composite coverage with nulls greatly decreased from those of the SPS-12pattern. Both radars operate in a search mode,automatic detection systems are associated with each radar,and the detection information is integrated via the tracking system. Height information is provided on targets designated by either the radar operator or the tracking computer. Three automatic detectors, a generalized sign nonparametric processor with adaptive thresholding, a rank detector,and a log-Raleigh detector,were designed. Using Monte Carlo techniques,probability of detection curves and angular accuracy curves were generated for these detectors. An unexpected result was little difference between the log-Rayleigh and rank detectors. (Author)
