Wideband MIMO Systems: Signal Design for Transmit Beampattern Synthesis
IEEE Transactions on Signal Processing, 2011 The usage of multi-input multi-output (MIMO) systems such as a MIMO radar allows the array elements to transmit different waveforms freely. This waveform diversity can lead to flexible transmit beampattern synthesis, which is useful in many applications such as radar/sonar and biomedical imaging.

Robust Transmit Beampattern Matching Synthesis for MIMO Radar
Electronics Letters, 2017 A robust transmit beampattern matching synthesis approach is described for a multiple‐input and multiple‐output radar with manifold vectors perturbation. This synthesis technique minimises the worst‐case matching performance between the transmit beampattern and the desired beampattern (in a least absolute deviations sense), through designing the ...

Array Pattern Synthesis Using Sparse Representation of Beampattern
Electronics Letters, 2012 A new array pattern synthesis method is proposed by using the concept of a sparse representation of beampattern, in which array pattern synthesis is achieved by evaluating the sparsity of beampattern and combining with a set of constraints on magnitude response.

BA-Based Low-PSLL Beampattern Synthesis in the Presence of Array Errors
IEEE Access, 2022 In practical scenarios, there are always array errors, which would increase the sidelobe level (SLL) of the array and distort the performance of the electronic devices consequently.

Beampattern analysis of frequency diverse array radar: a review
EURASIP Journal on Wireless Communications and Networking, 2021 Electronic beam steering is an essential feature of state-of-the-art radar systems. Conventional phased array (PA) radars with fixed carrier frequencies are well-known for electronically steering their beam with high directivity.
