PROJECT TITLE :

IRCI free colocated mimo radar based on sufficient cyclic prefix OFDM waveforms

ABSTRACT:

In this paper, we have a tendency to propose a cyclic prefix (CP)-based multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) range reconstruction methodology and its corresponding MIMO-OFDM waveform style for colocated MIMO radar systems. Our proposed MIMO-OFDM waveform design achieves the most signal-to-noise ratio gain when the vary reconstruction, and its peak-to-average power ratio within the discrete time domain is also optimal, i.e., zero dB, when Zadoff-Chu sequences are used in the discrete frequency domain because the weighting coefficients for the subcarriers. We tend to additionally investigate the performance when there are transmit and receive digital beamforming (DBF) pointing errors. It's shown that our proposed CP-primarily based MIMO-OFDM vary reconstruction is interrange cell interference free no matter whether or not there are transmit and receive DBF pointing errors or not. Simulation results are presented to verify the speculation and compare it with the conventional OFDM and linear frequency modulation colocated MIMO radars.
