A study on multi-stage tracking technique in T/R-R bistatic system

When the communication link of a T/R-R bistatic radar system is affected by external interference, the number of usable measurements in it is variable. Therefore it is necessary to study some tracking algorithms concerning with different sets of measurement data. The multi-stage tracking technique proposed in the paper makes full use of measurement data in T/R and R station under different condition, as a result the tracking precision of 3-D moving targets is increased. The performance of these algorithms is evaluated with the help of computer simulation for typical target paths.
