A Low-Cost Chaotic Radar Signal Design Method

Abstract:

The matched filter of chaotic radar system proposed by Ned J. Corron can be implemented through low-cost analog devices. But the spectrum of transmitted signal of this system is dispersion, causing signal in the process of propagation prone to spectrum leaked. To solve the problem, this paper proposes a low-cost signal design method. In transmitter, making chaotic signal become a band-limited signal by filtering to shape the spectrum; in receiver, using synchronization and filtering to recover the chaotic signal. The proposed method is implemented with low-cost analog devices; in addition, the method is still valid when the SNR is as low as-20dB.
