In this paper, we propose a novel fuzzy-control-based particle filter (FCPF) for maneuvering target tracking, which combines the advantages of standard particle filter (SPF) and multiple model particle filter (MMPF). That is, the SPF is adopted during non-maneuvering movement while the MMPF is adopted during maneuvering movement. The key point of the FCPF is to use a fuzzy controller, which could imitate the thoughts of human beings in some degree, to detect the target’s maneuver and use a backward correction sub-algorithm to alleviate the performance degradation of MMPF caused by detection delay. Simulation results indicate that the proposed algorithm has a much better tracking accuracy than the SPF while keeps approximately equal computational complexity. Compared with MMPF, both algorithms have no tracking lost, but the tracking accuracy of the proposed FCPF is a little better than the MMPF, and the FCPF consumes about 66% computation time of the MMPF. Thus, the proposed algorithm offers a more effective way for maneuvering target tracking.

The electromagnetic coupling coefficient is an important parameter in circuit modeling and simulation because it characterizes the transducer and useful for deducing equivalent circuits. In this paper, we proposed a numeric coupling coefficient extraction method based on perturbation theory and commercially available CST software of solving the coupling coefficient of the rectangular waveguide resonator, which is coupling with a coaxial cable. Simulation results indicate that this method is consistent with the theoretical method, and it is commonly used for rectangular or cylindrical cavities. Thus, the proposed method could offer an effective way of solving coupling coefficients extraction problem for cavity resonators.

This paper presents a novel millimeter wave power- combining system which can be fabricated with modern packaging technology and compatible with CMOS process. The system is comprised of a silicon integrated waveguide (SIW) resonator coupled with numerous λ/4 standing wave resonators, all of which can be fabricated by using via holes in 3-D packaging level. The coupling between the SIW resonator and the λ/4 standing wave resonators can be fabricated by eroding slots in the metal layer. An example system operating at 77GHz is illustrated and simulation results of electromagnetic field distribution in the SIW resonator and around the λ/4 standing wave resonators from professional electromagnetic simulation tool are presented. It is shown that the resonant frequency and phase of these λ/4 standing wave resonators are controlled by the SIW resonator and the power of all these λ/4 standing wave resonators can be combined in the SIW resonator. The SIW resonator operates in TE102 mode and has a quality factor of more than 500, which is much higher than that of each independent λ/4 standing wave resonators with quality factor of about 150. Thus the proposed power-combining system fabricated in packaging level can work effectively and features a lower loss and high quality factor.

A novel millimeter wave resonant system
Abstract: A novel millimeter wave resonant system is presented. The system is comprised of a silicon integrated waveguide resonator and numerous λ/4 standing wave resonators, coupled together by magnetic field as a whole. The resonant frequency and phase of these λ/4 standing wave resonators are controlled by the Silicon Integrated Waveguide Resonator. The merits of this millimeter wave resonant system are: small loss, high quality factor, compatibility with wafer level package technology and being able to be made in the package structure of the integrated circuit. This system can beeasily combined with the CMOS technique and it can synthesis power of lots of λ/4 standing wave resonators with high efficiency so that higher power of millimeter wave could be obtained.
