TL;DR: It is demonstrated that the steering vectors of signals are almost orthogonal to the interference-noise subspace, enabling this technique to suppress the tow ship interference as well as retain the signal output, making it a superior approach to eliminate the tow ships interference’s azimuth spread.

TL;DR: A simulated annealing-based algorithm is proposed for binary weighted beamforming, achieving 4.43 dB average side lobe reduction and 20 dB extra depth in presence of a jammer, utilizing 66.7% of array elements with increased main lobe width.

TL;DR: In this article , the authors proposed a top-down task planning algorithm based on greedy policy to tackle the problem of task planning in UAV cooperative detection, where the core idea of the proposed method lies in that they choose optimal detection trace from all trace candidates during each planning step in a greedy manner via a predefined performance indicator, and also proposed a simple but effective procedure for generate detection trace candidates by corner points and nearest border points extraction.

TL;DR: This paper presents a broadband aperture extension approach of a passive sonar array based on multi-dimension autoregression (AR) model, integrated with failure element compensation, designed to recover the failure array elements to ensure the feasibility and accuracy of AR modeling and virtual element prediction.
