چکیده
With the wide use of GPS, it becomes more and more important to improve the positioning accuracy. The GPS signal is very weak, and can be easily interfered. Space-time adaptive processing(STAP) can suppress the jamming not only in the temporal domain, but also in the spatial domain. STAP has now become a good candidates for jamming mitigation in GPS. In order to evaluate the performance of various kinds of STAP algorithms, and to develop the novel STAP algorithms. we need to simulate space-time array GPS data with high fidelity and the software GPS receiver. This paper mainly presents a simulation method for space-time GPS data, as well as the simulation of some typical kinds of jammers. The simulation method for software GPS receiver is also introduced. The data that after the process of STAP is computed by the simulated GPS receiver. The simulation results show that the simulation tool is a good platform for the development of STAP algorithms.

This paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. A novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. Parameters of the fuzzy estimator are adapted to minimize the estimat...

A major challenge in using GPS guidance for aircraft final approach and landing is to reject interference that can jam reception of the GPS signals. Antenna arrays, which use space–time adaptive processing (STAP), significantly improve the signal to interference plus noise ratio, but at the possible expense of distorting the received signals, leading to timing biases that may degrade navigation...
