Abstract

This paper describes the algorithms that Arete with support from the Office of Naval Research (ONR) is developing for shipboard infrared search and track (SIRST) detection of low-observable targets, such as subsonic, sea-skimming cruise missiles. Early detection of low signal-to-noise (SNR) targets (6 - 10 dB) is provided by Arete's Bayesian field tracker (BFT), which is a track- before-detect algorithm. Candidate detections from the BFT are used to initialize the position, velocity and likelihood of candidate tracks in a peak likelihood track-after-detect tracker. False alarm mitigation is accomplished in part by requiring the temporal evolution of a candidate track to be consistent with that of an incoming sea-skimming cruise missile. The overview of the algorithms involved in these trackers and results from both real targets and simulated targets injected into real images are presented.
