Minimum Norm Method for Linear and Planar Sparse Arrays
Tyler M. Trosclair, Kaushallya Adhikari
Coprime and nested arrays are sparse arrays with enhanced degrees of freedom, which can be exploited in direction of arrival estimation using algorithms such as product processing,…
Product Processing for Tapered Sparse Arrays
Daniel Sartori, Kaushallya Adhikari
The product processor output has recently been introduced as a spatial power spectral density estimate, unifying product arrays such as coprime arrays, nested arrays, and standard…
Absolute Eigenvalues-Based Covariance Matrix Estimation for a Sparse Array
Kaushallya Adhikari
The ensemble covariance matrix of a wide sense stationary signal spatially sampled by a full linear array is positive semi-definite and Toeplitz. However, the direct augmented cova…
Matched Illumination Waveforms using Multi-Tone Sinusoidal Frequency Modulation
Kaushallya Adhikari, David A. Hague
This paper explores the design of constant modulus Matched-Illumination (MI) waveforms using the Multi-Tone Sinusoidal Frequency Modulation (MTSFM) waveform model. MI waveforms are…
Sparse Sensing with Semi-Coprime Arrays
Kaushallya Adhikari
A semi-coprime array (SCA) interleaves two undersampled uniform linear arrays (ULAs) and a element standard ULA. The undersampling factors of the first two arrays are and…
