N2 - Spectrum-efficient frequency shift keying (FSK) radar has been investigated previously for range tracking and localization of both moving and stationary human targets. Traditionally, both in-phase (I) and quadrature (Q) channels are used for range tracking of moving targets using FSK radar. In this paper, a single channel moving target tracking method is proposed, which brings the benefit of reduced circuit complexity at the trade-off of half of the maximum unambiguous range. Range tracking theory including quadrature channel demodulation, single channel demodulation, and phase difference correction are discussed. Simulation is provided to validate the proposed tracking method. Experiments demonstrate that the target trajectory can be successfully measured with the proposed single channel tracking method if it is within half maximum unambiguous range of an I/Q channel system, while the range estimation will be inaccurate if the target movement is beyond the limit of half maximum unambiguous range.
