A Novel Method of Using Chaotic Sequences in MIMO Radar for Multiple Targets Detection

摘要：

　　Based on the sensitive dependence on initial conditions and good auto-correlation of chaotic sequences,a method is proposed to increase the resolution of multiple-input multiple-output (MIMO) radar for multiple targets detection with chaotic sequences.Chaotic waveform set can be generated by chaotic sequences from different initial values.It is uncorrelated between auto-correlation sidelobes of different chaotic waveforms,at the same time,it is uncorrelated between cross-correlation of different chaotic waveforms too.Therefore,multiple pulse compression accumulation can help to reduce auto-correlation sidelobes and cross-correlation effects in MIMO radar effectively,the output has low peak sidelobe value and the resolution of multiple targets detection is increased.Finally,simulation results show the effectiveness of this method.
