Abstract: |
In order to achieve both high precision and high efficiency for the radars’ operational effectiveness evaluation, the paper proposes a refined functional simulation method. The radar detection processing model strictly imports the influences of radar system, site elevation, target motion, RCS fluctuation, electronic jamming, etc., then precisely calculates targets’ SINR and detection rate, and finally generates the plot data whose precision approaches the signal?level simulation models. The plot?track processing model performs false detection reduction, plots centroid, track initialization, plot?to?track association, and track filtering in compliance with realistic software. The radar behavioral model implements the jamming recognition and anti?jamming strategies in compliance with actual rules. Comparing with traditional functional simulations, the method in this paper can accurately simulate the anti?jamming performance under complicated environment. |
