Abstract:
A new application of chaos to electrical engineering is developed. By creating chaotic binary sequences, and using these as pulse compression codes for radar, many advantages are realized over codes that are presently used. These chaotic codes are generated by quantizing the iterates of one-dimensional chaotic difference equations to two levels. Being chaotic, these binary sequences are unpredictable in the long term, and are nonperiodic or can have periods of billions of bits. The autocorrelations of the sequences are derived, then the sequences are applied to radar, where the unpredictable and nonperiodic nature of these sequences is exploited. It is shown that chaotic codes offer advantages in maximum range performance, range resolution, low probability of intercept, and probability of false alarm compared to codes presently used.
