Abstract
A descriptor has the capabilities of providing state vectors to describe movable platforms, extended objects, information collecting and surveillance systems. An aggregator furnishes the descriptor with abilities to deliver the state vectors in dynamical situations of instabilities and chaos. The former comprises navigation antennas, optical RF link systems, and processing center for delivering the state vectors from received navigation RF signals. The latter comprises an RF delay loop for aggregating a train of RF signals into a single RF pulsed signal and means for outputting the pulsed signal for analysis. The aggregator has many applications. For instance, an aggregator is able to unscramble pseudo random signals with partial codes and to enhance the statistics of weak transient signals.
