In this paper, we propose chaotic wireless communication system using digital retrodirective array antenna (RDA) for improving security and receive performance at receiver. Chaotic modulation schemes have studied for reducing the probability of interception and interrupt. As a result, chaotic communication systems have enhanced security. But the receive performance at receiver is degraded. We propose digital RDA system based on chaotic modulation for improving the reception performance while maintaining the security. Simulation results show that to overcome degradation of reception performance in CDSK, digital RDA with array elements up to five is required compared to BPSK modulation scheme.
