Real-time ranging of the six orientational targets by using chaotic polarization radars in the three-node VCSEL network.

We propose a novel scheme of the real-time ranging for the six orientational targets based on the vertical cavity surface-emitting laser (VCSEL) network with three nodes. In the scheme, we explore a method to realize the globally complete chaotic synchronization (GCCS) of the network with different channel delays. Under the GCCS, we use the six chaotic polarization radars for the ranging of the six orientational targets based on Hilbert transform theory. It is found that the ranging of the six orientational targets has good performance, such as real-time stability and high accuracy, and the absolute errors of the ranging reach millimeter magnitude. Moreover, all relative errors are small and less than 11%.
