Access Track-before-detect procedures for detection of extended object Ling Fan * , Xiaoling Zhang and Jun Shi Abstract In this article, we present a particle filter (PF)-based track-before-detect ... than one resolution cell of range even for SNR = 12 dB. The reason is that estimation of the target posi- tion is the position of the centre of the extended target (see...

... the traction problems for Lam´e system in a multiply connected bounded domain of R n , n ≥ 2. It hinges on the theory of reducible operators and on the theory of differential forms. Differently from ... solution of the Dirichlet problem in the form of a simple layer potential. This approach leads to an integral equation of the first kind on the boundary which can be treated in diffe...

... point of view. Accordingly, we formulate GUTPC as follows. Let p denote the power vector of all links, let p i denote the transmit power of link i, then the net utility function U i (p) of link ... the design of C i (p i ) is crucial for the net utility func- tion. Basically, C i (p i ) should be an increasing function of p i to charge the nodes for their transmit power in ter...
