for Radar, Sonar, and Communications discusses various design approaches of sparse arrays, including those seeking to increase the corresponding one-dimensional and two-dimensional virtual array apertures, as well as others that configure the arrays based on solutions of constrained minimization problems....
Sparse array technology is being investigated to develop a sonar requiring the minimal number of signal processing channels while maintaining the beamwidth and sidelobe structure required for high resolution imaging. Beamwidth and sidelobe structure are examined as a function of transducer element count, ...

This Special Issue is intended to encourage high-quality research in array signal processing techniques with sparse arrays and its applications in radar, sonar, wireless communications, and other fields. Authors are invited to submit papers presenting new research to tackle the potential problems in em...
The uniform linear arrays (ULAs), with half-wavelength inter-antenna spacing, are commonly used for direction finding. However, the degrees of freedom (DOFs) of ULAs are limited in the sense that the number of signals to be processed should be less than the number of antennas. More ...

Section 3 details the SCA for arrays designed freely alongside the hybrid design approach and the associated modified SCA optimization. Section 4 explains the matrix completion approach. In section 5, with the aid of Monte Carlo simulations, we compare the performance of hybrid-designed arrays viz ...
Technologies for configuring a two-dimensional (2D) semi-regular sparse array of sonar detector elements are disclosed. The 2D array may be formed from a non-uniform one-dimensional (1D) array of non-uniform arrays. The 2D array may be composed of two or more 1D arrays with non-uniform sp...
Arrays of transducers are commonly used in such diverse fields as radio astronomy, seismic exploration, sonar, radar, communications and ultrasound imaging. The primary function of an array is to transmit and/or receive electromagnetic or acoustic energy over a specified region of space. Individual ...
