1. An Automatic Dependent Surveillance Broadcast (ADS-B) system comprising:
a plurality of ADS-B terrestrial stations, each ADS-B terrestrial station comprising an antenna and wireless circuitry associated therewith defining a station gain pattern; and
a controller comprising
a variational autoencoder (VAE) configured to
compress station gain pattern data from the plurality of ADS-B terrestrial stations,
create a normal distribution of the compressed data in a latent space of the VAE, and
decompress the compressed station pattern data from the latent space; and
a processor coupled to the VAE and configured to
process the decompressed station pattern data using a probabilistic model selected from among a plurality of different probabilistic models based upon a game theoretic reward matrix,
determine an anomaly from the processed decompressed station pattern data, and
generate an alert based upon the determined anomaly.
