Sparse Sampled Logistic Chaos-Based Frequency Modulated Signals For Mimo Radar

To promote the signals orthogonal performance which is quite important in MIMO(Multi-Input Multi-Output) system, a sparse sampling method is proposed for Logistic chaos-based frequency modulated signals adapting for MIMO radar. Theoretical analysis is deduced, and better correlation performance including lower range autocorrelation side-lobe peak level as well as range cross-correlation peak level can be obtained. The numerical results are presented to verify the proposed method.
