Beam Steering by Lag Synchronization in Ultra-Wide Bandwidth, Chaotic Arrays

摘要

We introduce a new method for beam steering in ultra-wide bandwidth arrays. The approach avoids the need for tunable microwave delays by using lag synchronization in a linear array of locally coupled chaotic oscillators. Steering is controlled by tuning the natural frequency of the oscillators and is analytically equivalent to first order to using explicit delay elements. Using chaotic rf circuits oscillating at tilde20MHz, we show both lag and lead synchronization can be practically controlled in rf arrays.
