Qualitative and quantitative characteristics of deghosting in advanced radar systems
L.R. Paradowski · 2003
Deghosting, i.e. elimination of false targets during data processing in multi-sensor tracking of jamming targets, is a crucial process for effective use of air defence systems. It is particularly important for radar systems operating in passive mode because of their excellent properties against present-day electronic warfare techniques and tactics (especially jamming equipment and anti-radiation missiles). A deghosting algorithm based on bearing association/compounding strategy is outlined. A method of deghosting effectiveness evaluation using the ghost eliminator operating characteristic (reference to the receiver operating characteristic from statistical theory of signal detection) is presented. Such an approach enables to compare performances of various deghosting procedures in different operational conditions or scenarios.
