Two Novel Low Mutual Coupling Sparse Array Configurations: Combining Multiple Uniform Linear Arrays and Additional Sensors

Abstract: The mutual coupling (MC) effect between sensors is a critical factor in sparse array (SA) design, substantially affecting direction-of-arrival (DOA) estimation performance. In this paper, we ...

Model-Based Learning for DOA Estimation with One-Bit Single-Snapshot Sparse Arrays

We address the challenging problem of estimating the directions-of-arrival (DOAs) of multiple off-grid signals using a single snapshot of one-bit quantized measurements. Conventional DOA estimation ...
