Low-Cost Turntable Designed for RF Phased Array Antenna Active Element Pattern Measurement
Rebekah Edwards, Taylor Martini, Jonathan E. Swindell +5
Accurate antenna array calibrations and measurements of aspects such as active element pattern (AEP) are critical for enabling integrated sensing and communication (ISAC) technolog…
Implementation of a Directional Modulation Testbed for Reconfigurable Transmitters for Spatially Agile MIMO Systems
Jonathan E. Swindell, David W. Cox, Rebekah Edwards +5
This paper demonstrates the implementation and validation of a microwave testbed for directionally modulated transmission. Directional modulation enables multiple communication and…
Growing Into an Adaptive and Reconfigurable Paradigm for Spectrum Sharing
Charles Baylis, Douglas Sicker, Austin Egbert +4
A significant movement from rigid use of the wireless spectrum toward adaptive and reconfigurable spectrum use has been prompted by increasing spectral crowding. Some bands have mo…
Algorithmic Information Forecastability
Glauco Amigo, Daniel Andrés Díaz-Pachón, Robert J. Marks +1
The outcome of all time series cannot be forecast, e.g. the flipping of a fair coin. Others, like the repeated {01} sequence {010101...} can be forecast exactly. Algorithmic inform…
Changepoint Detection for Real-Time Spectrum Sharing Radar
Samuel Haug, Austin Egbert, Robert J. Marks +2
Radar must adapt to changing environments, and we propose changepoint detection as a method to do so. In the world of increasingly congested radio frequencies, radars must adapt to…
In-Situ Assessment of Array Antenna Currents for Real-Time Impedance Tuning
Charles Baylis, Adam Goad, Trevor Van Hoosier +2
Impedance tuning has shown promise to maximize output power, gain, or efficiency for transmitter amplifier devices in changing frequency or array environments. Using impedance tuni…
Dilated POCS: Minimax Convex Optimization
Albert R. Yu, Robert J. Marks, Keith E. Schubert +4
Alternating projection onto convex sets (POCS) provides an iterative procedure to find a signal that satisfies two or more convex constraints when the sets intersect. For noninters…
Classification of Common Waveforms Including a Watchdog for Unknown Signals
C. Tanner Fredieu, Justin Bui, Anthony Martone +3
In this paper, we examine the use of a deep multi-layer perceptron model architecture to classify received signal samples as coming from one of four common waveforms, Single Carrie…
Cascade Watchdog: A Multi-tiered Adversarial Guard for Outlier Detection
Glauco Amigo, Justin M. Bui, Charles Baylis +1
The identification of out-of-distribution content is critical to the successful implementation of neural networks. Watchdog techniques have been developed to support the detection…
Range Improvement in Single-Beam Phased Array Radars by Amplifier Impedance Tuning
Pedro Rodriguez-Garcia, Jack Sifri, Caleb Calabrese +2
Significant radar range degradation can be incurred due to variations in antenna impedance from changing array scan angle. Element-wise reconfigurable impedance tuners can be used…
