Performance evaluation of multisensor track formation algorithms in urban environment

Urban areas constitute complex environments for radars. This paper deals with the problem of radar track formation for flying targets in low-level airspace over urban environment, particularly for artillery rockets and mortars. The presented experiments address the problem of sensitivity of two track formation algorithms, based on multisensor versions of the multiple hypothesis tracking approach (MHT) and the Hough transform, to radar performance degradation caused by urban environment. Simulation result show superiority of the MHT track initiator for virtually all performed tests. Moreover, multisensor detection can significantly reduce number of false alarms at the expense of only slight delay of track detection.
