Using Particle Filter for Estimating Velocity of Maneuvering Target Being Tracked by Passive Radar

Syrian Journal for Science and Innovation
Tracking a target is achieved by estimating its range and velocity, and this process has two types: Bistatic Tracking and Cartesian Tracking. In a passive radar system, the bistatic tracking is achieved by processing the bistatic geometry “One non ...

Mathematical models and simulations of phase noise in phase-locked loops [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2007
Phase noises in Phase-Locked Loops (PLLs) are a key parameter for communication systems that contribute the bit-rate-error of communication systems and cause synchronization problems.

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction

Advanced Functional Materials, EarlyView.
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...
