Harnessing Holes for Spatial Smoothing with Applications in Automotive Radar
Yinyan Bu, Robin Rajamäki, Pulak Sarangi +1
This paper studies spatial smoothing using sparse arrays in single-snapshot Direction of Arrival (DOA) estimation. We consider the application of automotive MIMO radar, which tradi…
Effect of Beampattern on Matrix Completion with Sparse Arrays
Robin Rajamäki, Mehmet Can Hücümenoğlu, Pulak Sarangi +1
We study the problem of noisy sparse array interpolation, where a large virtual array is synthetically generated by interpolating missing sensors using matrix completion techniques…
Super-resolution with Binary Priors: Theory and Algorithms
Pulak Sarangi, Ryoma Hattori, Takaki Komiyama +1
The problem of super-resolution is concerned with the reconstruction of temporally/spatially localized events (or spikes) from samples of their convolution with a low-pass filter.…
Super-resolution with Sparse Arrays: A Non-Asymptotic Analysis of Spatio-temporal Trade-offs
Pulak Sarangi, Mehmet Can Hucumenoglu, Robin Rajamaki +1
Sparse arrays have emerged as a popular alternative to the conventional uniform linear array (ULA) due to the enhanced degrees of freedom (DOF) and superior resolution offered by t…
