14th conference on signal and data processing of small targets
作者: Sworder, DD Boyd, JE Univ Calif San Diego Dept Elect & Comp Engn La Jolla CA 92093 USA
Model-based. path estimation algorithms are commonly derived from a linear kinematic equation and an expansive observation model. the premise that the measurement region is all-inclusive simplifies the performance ana... 详细信息

14th conference on signal and data processing of small targets
作者: Drummond, OE CyberRnD Inc Culvar City CA 90230 USA
Track and tracklet fusion filtering is complicated because the estimation errors of tracks from two sources for the same target may be cross-correlated. this cross-correlation of these errors should be taken into acco... 详细信息

作者: Chen, H Kirubarajan, T Bar-Shalom, Y Pattipati, KR Univ Connecticut Dept Elect & Comp Engn Storrs CT 06269 USA
In this paper the track initiation problem is formulated as multiple composite hypothesis testing using maximum likelihood estimation with probabilistic data association (ML-PDA), an algorithm known to work under very... 详细信息

14th conference on signal and data processing of small targets
作者: Koch, W FGAN FKIE D 53343 Wachtberg Neuenahrer Strasse 20 Germany
Collectively moving ground targets are typical of a military ground situation and have to be treated as separate aggregated entities. For a long-range ground surveillance application with airborne GMTI radar we in par... 详细信息

作者: Lim, ET Shue, L Venkarteswarlu, R Nanyang Technol Univ Ctr Signal Proc Singapore 639798 Singapore
the problem of detecting small target in IR imagery has attracted much research effort over the past few decades. As opposed to early detection algorithms which detect targets spatially in each image and then apply tr... 详细信息

作者: Gray, JE McCabe, DH USN Ctr Surface Warfare Dahlgren Div Syst Res & Technol Dept Dahlgren VA 22448 USA
Sensor data fusion has long been recognized as a means to improve target tracking. Common practice assumes that the sensors used are synchronous (i.e., perform the, same operation at the identical time), take measurem... 详细信息
