Class TLcdASTERIXSacSicRecordFilter

java.lang.Object
com.luciad.format.asterix.TLcdASTERIXSacSicRecordFilter
All Implemented Interfaces:
ILcdASTERIXRecordFilter
public class TLcdASTERIXSacSicRecordFilter extends Object implements ILcdASTERIXRecordFilter

ILcdASTERIXRecordFilter implementation that allows you to filter the ASTERIX records by data source (for instance, by the radar system that picked them up). The data source is defined by a SAC/SIC code (System Area Code / System Identification Code).

When multiple radar systems report on the same tracks in turn, a zig-zag effect might show up because of slight deviations in either radar system. To avoid this, filter out reports of either radar system using this filter.

Since:
2012.0
