Sequence design to minimize the peak sidelobe level
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016Sequences with low aperiodic autocorrelation sidelobes are well-known to have extensive applications in active sensing and communication systems. In this paper, we consider the sequence design problem of minimizing the lp-norm of the autocorrelation side-lobes, which can then be used to minimize the peak sidelobe level (PSL) criterion.

Control of peak sidelobe level in adaptive arrays
IEEE Transactions on Antennas and Propagation, 1996Adaptive beamforming techniques are now widely used to reject interference (jammer/clutter) signals in radar, communication, and sonar applications. In adaptive arrays using the sample matrix inversion (SMI) algorithm, inadequate estimation of the covariance matrix results in adaptive antenna patterns with high sidelobes and distorted mainbeams.

Minimum local peak sidelobe level waveform design with correlation and/or spectral constraints
Signal Processing, 2020Abstract The problem of designing waveforms with specified aperiodic/periodic correlation and spectral properties has received much attention because of its wide applicability in sonar, radar, and communications. In particular, a waveform with low peak sidelobe level (PSL) of autocorrelation can improve the detection performance of a weak target ...

Efficient construction of polyphase sequences with optimal peak sidelobe level growth
2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017Sequences with good correlation properties form an integral part of many active sensing and communication systems. Although polyphase sequence sets with optimal peak sidelobe level (PSL) growth have been known for years, it has been a long-standing problem to construct polyphase sequences with small PSL growth.

Designing Unimodular Sequence With Low Peak of Sidelobe Level of Local Ambiguity Function
IEEE Transactions on Aerospace and Electronic Systems, 2019This paper considers the problem of designing unimodular sequence with low peak of sidelobe level of local ambiguity function. The optimization problem is difficult because of the mixed nonconvex unimodulus and highly nonlinear fourth-order polynomial-like constraints.

A New Search for Optimal Binary Arrays with Minimum Peak Sidelobe Levels
2005The group structure of the 2-dimensional sidelobe-invariant transformations for binary arrays is characterized. The design of an efficient exhaustive backtracking search algorithm, which exploits such group structure to reduce the search space and, in the meantime, applies the partially determined autocorrelation values as backtracking conditions, is ...

Peak sidelobe level gumbel distribution for arrays of randomly placed antennas
2015 IEEE Radar Conference (RadarCon), 2015Extreme Value Theory (EVT) is used to analyze the peak sidelobe level distribution for array element positions with arbitrary probability distributions. Computations are discussed in the context of linear antenna arrays using electromagnetic energy. The results also apply to planar arrays of random elements that can be transformed into linear arrays ...

Steepest descent method for minimizing the peak sidelobe level of hopped-frequency waveform
2017 IEEE Radar Conference (RadarConf), 2017Hopped-frequency waveform achieves high range resolution by transmitting a burst of narrowband pulses spanning the desired bandwidth. As its frequencies are irregularly or even sparsely distributed, hopped-frequency waveform could obtain a wider bandwidth with fixed pulses number and shows stronger anti-jamming ability than the linear stepped-frequency
