Abstract
Transmit sequence design plays a significant role in multiple-input multiple-output (MIMO) radar to suppress correlation function side-lobe levels. This paper investigates two practical constraints, namely, constant envelope constraint to reduce the effect of nonlinear amplifiers, and low side-lobe levels to reduce the effect of interference among various transmitting sequences. To facilitate this, new Legendre sequences (L-seq) are designed that uses Legendre orthogonal polynomial (LOP). Superiority of the proposed L-seq is proven for peak side-lobe level (PSL) and cross-correlation level (CCL) performance parameters. Further, the signal cross-interference in MIMO radar is minimized by generating orthogonal L-seq. The impact of designed L-seq on the delay-Doppler plane is observed using the ambiguity function (AF). Simulation results show that the proposed L-seq has a constant envelope and suppressed side-lobe levels compared to the existing popular methods.
