Widely Separated MIMO Radar Using Matrix Completion
Shunqiao Sun, Yunqiao Hu, Kumar Vijay Mishra +1
We present a low-complexity widely separated multiple-input-multiple-output (WS-MIMO) radar that samples the signals at each of its multiple receivers at reduced rates. We process…
Sparse Array Design for Direction Finding using Deep Learning
Kumar Vijay Mishra, Ahmet M. Elbir, Koichi Ichige
In the past few years, deep learning (DL) techniques have been introduced for designing sparse arrays. These methods offer the advantages of feature engineering and low prediction-…
Octonion Phase Retrieval
Roman Jacome, Kumar Vijay Mishra, Brian M. Sadler +1
Signal processing over hypercomplex numbers arises in many optical imaging applications. In particular, spectral image or color stereo data are often processed using octonion algeb…
Inverse Unscented Kalman Filter
Himali Singh, Kumar Vijay Mishra, Arpan Chattopadhyay
Rapid advances in designing cognitive and counter-adversarial systems have motivated the development of inverse Bayesian filters. In this setting, a cognitive 'adversary' tracks it…
Moving Target Detection via Multi-IRS-Aided OFDM Radar
Zahra Esmaeilbeig, Arian Eamaz, Kumar Vijay Mishra +1
An intelligent reflecting surface (IRS) consists of passive reflective elements capable of altering impinging waveforms. The IRS-aided radar systems have recently been shown to imp…
Near-Field Low-WISL Unimodular Waveform Design for Terahertz Automotive Radar
Arian Eamaz, Farhang Yeganegi, Kumar Vijay Mishra +1
Conventional sensing applications rely on electromagnetic far-field channel models with plane wave propagation. However, recent ultra-short-range automotive radar applications at u…
Multi-Antenna Dual-Blind Deconvolution for Joint Radar-Communications via SoMAN Minimization
Roman Jacome, Edwin Vargas, Kumar Vijay Mishra +2
In joint radar-communications (JRC) applications such as secure military receivers, often the radar and communications signals are overlaid in the received signal. In these passive…
Spatial Path Index Modulation in mmWave/THz-Band Integrated Sensing and Communications
Ahmet M. Elbir, Kumar Vijay Mishra, Asmaa Abdallah +2
As the demand for wireless connectivity continues to soar, the fifth generation and beyond wireless networks are exploring new ways to efficiently utilize the wireless spectrum and…
Inverse Cubature and Quadrature Kalman filters
Himali Singh, Kumar Vijay Mishra, Arpan Chattopadhyay
Recent research in inverse cognition with cognitive radar has led to the development of inverse stochastic filters that are employed by the target to infer the information the cogn…
Quantized Phase-Shift Design of Active IRS for Integrated Sensing and Communications
Zahra Esmaeilbeig, Arian Eamaz, Kumar Vijay Mishra +1
Integrated sensing and communications (ISAC) is a spectrum-sharing paradigm that allows different users to jointly utilize and access the crowded electromagnetic spectrum. In this…
Multi-Carrier Wideband OCDM-Based THz Automotive Radar
Sangeeta Bhattacharjee, Kumar Vijay Mishra, Ramesh Annavajjala +1
Automotive radars at the Terahertz (THz) frequency band have the potential to be compact and lightweight while providing high (nearly-optical) angular resolution. In this paper, we…
