Characterizing the Effects of Mixed Division Waveform Schemes in MIMO Radar
Oliver P. R. Kirkpatrick, Santiago Ozafrain, Christopher Gilliam +1
Direction of departure estimation in Multiple-Input-Multiple-Output (MIMO) radar is based on transmitting a set of orthogonal (or at least separable) waveforms, one per transmit el…
Physics-Informed Anomaly Detection of Terrain Material Change in Radar Imagery
Abdel Hakiem Mohamed Abbas Mohamed Ahmed, Beth Jelfs, Airlie Chapman +2
In this paper we consider physics-informed detection of terrain material change in radar imagery (e.g., shifts in permittivity, roughness or moisture). We propose a lightweight ele…
MIMO Array Calibration in Non-stationary Channels with Residual Surfaces and Slepian Spherical Harmonics
Oliver Kirkpatrick, Santiago Ozafrain, Christopher Gilliam +1
The fundamental mechanism driving MIMO beamforming is the relative phases of signals departing the transmit array and arriving at the receive array. If a propagation channel affect…
