This paper represents a new active phase array antenna for Ku-band mobile service that will be possible in satellite broadcasting service. The main idea for the antenna is to use minimum active array element with cost-effective one-dimensional subarrays with inclined pencil beam structure for 34 dBi gain. For this antenna, we also used the squint beam tracking algorithm. This tracking gives dif...

Learned, activity-specific motion models are useful for human pose and motion estimation. Nevertheless, while the use of activityspecific models simplifies monocular tracking, it leaves open the larger issues of how one learns models for multiple activities or stylistic variations, and how such models can be combined with natural transitions between activities. This paper extends the Gaussian p...

Recently, several researchers have studied a vector tracking loop, such as a vector delay lock loop (VDLL) and a vector frequency lock loop (VFLL), to obtain an improved tracking performance in GPS receiver [1~6]. The vector based tracking loop technique uses the correlation of each satellite signal and user dynamics. The receiver with the vector tracking loop can get enough total signal power ...

With the increasing number of satellite launches, especially in Low Earth Orbit (LEO), optical tracking can offer a convenient enhancement precision and availability. Spaceborne active illumination devices, such as LED payloads, significant improvement to observations, extending observability interval whole eclipse time performing optimized flash sequences for identification, orbit determinatio...

Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...
