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…
Autoencoder Watchdog Outlier Detection for Classifiers
Justin Bui, Robert J Marks
Neural networks have often been described as black boxes. A generic neural network trained to differentiate between kittens and puppies will classify a picture of a kumquat as a ki…
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…
