conference on signal and data processing of small targets 1999
作者: Zhu, ZF Liang, HC Pan, AJ Song, B Xu, GX Ni, GQ Beijing Inst Environm Features Beijing 100854 Peoples R China
Of particular interest are efficient algorithms of detection and acquisition of small targets with low signal-to-clutter ratio (SCR) for reality applications. Some algorithms like matched filtering (MF), dynamic progr... 详细信息

作者: Liang, HC Ni, GQ Zhu, ZF Xu, GX Pan, AJ Song, B Beijing Inst Technol Dept Optoelect Engn Beijing 100081 Peoples R China
It is a challenging problem to track point source targets and small extending ones in clutter. Only using single-image sensor is usually not adequate to meet the requirement of a multi-target tracking (MTT) system. Ca... 详细信息

作者: Liang, HC Ni, GQ Zhu, ZF Xu, GX Yu, YL Song, B Pan, AJ Beijing Inst Technol Dept Optoelect Engn Beijing 1000081 Peoples R China
The ground-target tracking with dual-image sensor is discussed in this paper. The mission scenario is that fighter and helicopter track tactical ground targets such as tank, armored car and articulated vehicle. The ai... 详细信息

conference on signal and data processing of small targets 1999
作者: Hewer, G Kenney, C Hanson, G Kuo, W Peterson, L USN Air Warfare Ctr China Lake CA 93555 USA
Wavelet-based detection algorithms are developed for detecting small targets in non-Gaussian clutter. A wavelet transform is applied to reduce spatial correlation of the clutter. An adaptive matched filter is applied ... 详细信息

conference on signal and data processing of small targets 1999
作者: Easthope, PF Adv Syst Architectures Ltd Alton GU34 4PU Hants England
This paper examines the determination of sensor biases by comparing multiple track outputs from spatially disparate platforms. In many cases, this can be achieved using least-squares methods, minimising the summed-squ... 详细信息

作者: Rozovskii, B Petrov, A Univ So Calif Ctr Appl Math Sci Los Angeles CA 90089 USA
The 3D matched filter proposed by Reed et al.(18) and its generalizations (e.g. banks of assumed velocity filters (BAVF)) provide a powerful processing technique for detecting moving low observable targets. This techn... 详细信息

Cruise missiles over land and sea cluttered background are serious threats to search and track systems. In general, these threats are stealth in both the infrared and radio frequency bands. That is, their thermal infr... 详细信息

作者: Doucet, A Gordon, NJ Univ Cambridge Signal Proc Grp Cambridge CB2 1PZ England
Whilst single model filters are sufficient for tracking targets having fixed kinematic behaviour, manoeuvring targets require the use of multiple models. Jump Markov linear systems (JMLS), i.e. linear systems whose pa... 详细信息

There are several methods reported in the literature for detecting dim targets against slowly moving clutter. However, each method has its own advantages and disadvantages. The challenge lies in reducing the 'fals... 详细信息

conference on signal and data processing of small targets 1999
作者: Perrella, A Glover, C Waugh, S Inst Def Analyses Alexandria VA 22311 USA
Adding new sensor metric information into a data fusion process does not always improve performance and can sometimes produce poorer results.(1.2) References 1 and 2 used examples to shaw that-in some instances and co... 详细信息
