Correlation of High Range Resolution Radar Signals of Aircraft with Modelled Data Stored in a Data Base

摘要

Performaning a Non-cooperative Identification function (NCl) depends mainly on the database with which measured radar data can be compared. This paper is concerned with one dimensional high range resolution signals of airborne targets and the possiblity of creating matching templates from modelled data for storage in a template library. Both the measured data and the modelled data are processed to obtain range profile plots as functions of the target aspect angle. The measured and simulated plots are compared for different targets. Further, both data sets are tested in such a way that cuts through the plots are taken as templates for profiles under a certain aspect angle az=y. These cuts are correlated with the original measured range profiles. Identification statistics are obtained from the correlation with the modelled data and with the measurement based data.
