BACKGROUND Real-time adherence monitoring is now possible through medication storage devices equipped with cellular technology. We assessed the effect of triggered cell phone reminders and counseling using objective adherence data on antiretroviral therapy (ART) adherence among Chinese HIV-infected patients. METHODS We provided ART patients in Nanning,(More)
Recent advances in scattering modeling and model-based decomposition theorem were reviewed. The notable achievements include orientation compensation processing, nonnegative eigenvalue constraint, generalized scattering models, complete information utilization, full-parameter inversion strategy, and the polarimetric-interferometric decomposition scheme.(More)
The overestimation of volume scattering power and the scattering mechanism ambiguity are still present in model-based decompositions even with the implementation of the deorientation processing. These effects are demonstrated and investigated. One possible reason is because of the limited dynamic range of the models themselves that are not fully satisfied(More)
The feature of micro-motion is one of the most effective features used for radar recognition in midcourse phase. At present, the study of feature extraction and recognition is usually based on the assumption that the micro-motion of the scattering center and warhead itself is the same, and the radar echo is sinusoid-FM signal. However, this assumption(More)
A novel main-lobe blanketing interference suppression method which named as spatial virtual multiple channel concurrent polarization filter technology is proposed. It processes sample data using the slow varied polarization property of a scanning antenna. The orthogonal polarized signal and polarization states of the receiving signal can be obtained. The(More)
Based on the ambiguity function, a novel signal processing method for the polarization measurement radar is developed. One advantage of this method is that the two orthogonal polarized signals do not have to be perpendicular to each other, which is required by traditional methods. The error due to the correlation of the two transmitting signals in the(More)
