Abstract

Based on the good correlation property of chaotic discrete frequency coding waveform (CDFCW), the method is proposed to increase the point target and close small target detection performance for multiple-input multiple-output (MIMO) radar. CDFCW can be generated by uniform quantifying and discrete frequency coding from chaotic sequence. Comparing the correlation property of four CDFCWs, the longer Tent discrete frequency coding waveform is chosen to increase the point target detection performance of MIMO radar. Meanwhile, the signal processing model of MIMO radar using CDFCW is built, multiple pulse compression accumulation can help to reduce the cross-correlation and auto-correlation side lobes of chaotic waveforms effectively, and the point target detection performance for MIMO radar is increased, especially for the close small target. Finally, simulation results show the effectiveness of the method.
