Time-frequency analysis for the localization of multiple moving targets using dual-frequency radars.
A dual-frequency radar, which estimates the range of a target based on the phase difference between two closely spaced frequencies, has been shown to be a cost-effective approach to accomplish both range-to-motion estimation and tracking. This approach, however, suffers from two drawbacks: it cannot...

Time-frequency analysis for the localization of multiple moving targets using dual-frequency radars. Zhang, Yimin. Amin, Moeness. Ahmad, Fauzia. A dual-frequency radar, which estimates the range of a target based on the phase difference between two closely spaced frequencies, has been shown to be a cost-effective approach to accomplish both range-to-motion estimation and tracking. This approach, however, suffers from two drawbacks: it cannot deal with multiple moving targets, and it has poor performance in noisy environments. In this letter, we propose the use of time-frequency signal representations to overcome these drawbacks. The phase, and subsequently the range information, is obtained based on the moving target instantaneous Doppler frequency law, which is provided through time-frequency signal representations. The case of multiple moving targets is handled by separating the different Doppler signatures prior to phase estimation. 2008 Villanova Faculty Authorship vudl:173744 IEEE Signal Processing Letters, vol. 15, pp. 777-780, 2008. en |
