Joint Target Tracking and Classification Using GSM-Based Passive Radar

Free registration required

Executive Summary

Unlike classical bistatic radars, passive radars make use of illuminators of opportunity to detect targets and estimate its parameters. However, GSM-based passive radar is not appropriate to target's location, because the GSM signal's bandwidth is small and insufficient to provide an acceptable range resolution. This paper present an approach to employ the GSM-based passive radar to joint target tracking and classification, using only direction of arrival and Doppler frequency shift of target signal's echo. The used algorithms combine extended Kalman filter, unscented Kalman filter and particle filter with multiple models. This three obtained algorithms, use only bearing and Doppler information to track and classify the moving target.
