Abstract
This paper describes the use of multiple hypothesis tracking (MHT) for the IRST Shipboard Self Defense application. This application features a highly variable clutter background, such as produced by sun glint, and maneuvering targets. The paper presents a technique for including features, such as measured SNR, in the track score. Performance results are presented for the case of a simulated missile target inserted in an ocean background. The paper presents computer timing and sizing results to show that recently developed algorithm efficiencies and computational capabilities make real-time MHT tracker operation feasible within the near future. A comparative study of track maintenance shows the significant potential performance improvement of MHT when compared with other data association methods.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
