Robust Adaptive Transmit Beamforming under the Constraint of Low Peak-to-Average Ratio
Sensors, 2022 In radar detection, in order to make the beam have variable directivity, a Capon beamformer is usually used. Although this traditional beamformer enjoys both high resolution and good interference suppression, it usually leads to high sidelobe and is ...

WCA-Based Low-PSLL and Wide-Nulling Beampattern Synthesis for Radar Applications
Remote Sensing, 2022 There are many unavoidable array errors in practical scenarios, which would drastically increase the sidelobe level (SLL) and distort the performance of radar systems accordingly.

Binary matrices of optimal autocorrelations as alignment marks [PDF]
, 2014 We define a new class of binary matrices by maximizing the peak-sidelobe distances in the aperiodic autocorrelations. These matrices can be used as robust position marks for in-plane spatial alignment. The optimal square matrices of dimensions up to 7 by

Sequence Design to Minimize the Weighted Integrated and Peak Sidelobe Levels [PDF]
IEEE Transactions on Signal Processing, 2016 Sequences with low aperiodic autocorrelation sidelobes are well known to have extensive applications in active sensing and communication systems. In this paper, we consider the problem of minimizing the weighted integrated sidelobe level (WISL), which can be used to design sequences with impulse-like autocorrelation and zero (or low) correlation zone ...

Test the Doppler Effects of Codes That Generated by Genetic Algorithm Using Ambiguity Function
Diyala Journal of Engineering Sciences, 2015 Using pulse compression at the receiver side of communication systems yields sidelobes around the mainlobe that permits the clutter to pass through it, and mask the desired signal.

Optimizing an array of antennas for cellular coverage from a high altitude platform [PDF]
, 2003 In a wireless communications network served by a high altitude platform (HAP) the cochannel interference is a function of the antenna beamwidth, angular separation and. sidelobe level.

The Peak Sidelobe Level of Families of Binary Sequences
2006 IEEE International Symposium on Information Theory, 2006 Summary: A numerical investigation is presented for the peak sidelobe level (PSL) of Legendre sequences, maximal length shift register sequences (\(m\)-sequences), and Rudin-Shapiro sequences. The PSL gives an alternative to the merit factor for measuring the collective smallness of the aperiodic autocorrelations of a binary sequence. The growth of the
