- The orthogonality of the transmitting signal is crucial for implementing multiple input multiple output(MIMO) radar system. The chaotic orthogonal discrete frequency coding waveform(DFCW) can be utilized to MIMO radar, and generate a large amount of orthogonal signal with random lengths and quantities. This paper applies the continuous chaotic system to analyze autocorrelation and crosscorrelation for the DFCW design of MIMO radar. The analysis indicates the side lobe peak of autocorrelation is 0.21, and the peak of crosscorrelation decreases with increasing the code length in DFCW without repetition of coding coefficients. The DFCW correlations are similar in continuous chaotic system and discrete chaotic system. In DFCW with repetition of coding coefficients, the side lobe peak of autocorrelation and the peak of crosscorrelation decrease as the code length is increased. The correlation of continuous chaotic system with coding coefficients repetition, is better than the correlation of discrete chaotic system, so it is the relatively ideal transmitting waveform for MIMO radar.
