Detecting Anomalous Behavior in Radar Data

Rook, Jayson Carr

Abstract Details

2021, Master of Science, Miami University, Computational Science and Engineering.
This project seeks to investigate and apply anomaly detection algorithms for a wideband receiver, that will flag anomalous radar behaviors sent by some transmitter external to the receiver's system. Flagging these anomalies will indicate to the receiver system that the radar's behavior has been reprogrammed, knowledge which is important for determining optimal countermeasures. The programs developed have investigated several approaches to accomplish this. Firstly, clustering methods like DBSCAN can group the observed pulses into distinct classes, reducing the problem to finding disruptions in patterns of numerical labels. Semi-supervised techniques like Hidden Markov Models and Long Short-Term Memories can be applied to learn these patterns for normal behavior and flag anomalies where the patterns are broken. Lastly, an unsupervised technique based on cross-correlations takes an alternative approach of flagging all the different behaviors in a sequence, without any initial training. Simulation results on test data demonstrate the functionality of these techniques, which are offered as potential suggestions for implementation in a real system.
