Robust mismatched filtering algorithm for passive bistatic radar using worst-case performance optimization Research Articles

Gang Chen, Jun Wang,chengang_xidian@163.com,wangjun@xidian.edu.cn

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 7,   Pages 963-1118 doi: 10.1631/FITEE.1900150

Abstract: detects targets by exploiting available local broadcasters and communication transmissions as illuminators, which are not designed for radar. The signal usually contains a time-varying structure, which may result in high-level range ambiguity sidelobes. Because the mismatched filter is effective in suppressing sidelobes, it can be used in a . However, due to the in the reference signal, the sidelobe suppression performance seriously degrades in a system. To solve this problem, a novel algorithm is developed using . In this algorithm, the influence of the low energy level in the reference signal is taken into consideration, and a new cost function is built based on . With this optimization, the mismatched filter weights can be obtained by minimizing the total energy of the ambiguity . Quantitative evaluations and simulation results demonstrate that the proposed algorithm can realize sidelobe suppression when there is a low-energy reference signal. Its effectiveness is proved using real data.

Research and Implementation of IP - VPN

Li Xiuzhong

Strategic Study of CAE 2002, Volume 4, Issue 3,   Pages 84-91

Abstract:

Recently, IP - VPN is proposed as a way satisfying large company´s inter-connect requirement because of the prevalence of Internet. But there are some problems to be solved, especially security and QoS. In this paper, one way of network-based VPN QoS is proposed based on analysis of some available QoS algorithms. For IP - VPN, now there are several mechanisms： VLL, VPRN, VPLS and VPDN. This paper places emphasis on VPRN and VPLS. Two kinds of VPRN: BGP/MPLS and VR are discussed and compared with each other. And besides, VLAN, one way of VPLS, is introduced.
