Adaptive Interference Suppression And Confrontation In Gps Receiver Is Empty

Adaptive filter technology that is developing had been successfully applied in GPS receiver anti-jamming implement. The application of space-time processing makes the GPS receiver anti-jamming capability more powerful. Estimation of GPS receiver anti-jamming performance is necessary, when adaptive space-time processing had been introduced in GPS receiver, and so is the method of intent attack to such technique.The difference in anti - jamming performance between GPS C/A and P(Y) - code due to code length difference is analyzed in the chapter two. That is important for the conclusion made from studing GPS C/A - code used for evaluating GPS P(Y) - code .The GPS receiver anti-jamming performance, when adaptive space-time processing had been introduced in, is analyzed in this paper for many circumstances. The analysis is made in two approaches, one of which is theoretic approach, and another is implement in computer simulation. Some useful conclusion had been made, which may be a background to analyze the GPS receiver anti-jamming performance. The investigation involves optimization problem in adaptive filter, and the special aspect in GPS receiver. The study of adaptive algorithm lay stress on LMS and LS/RLS.A method to jam the adaptive filter used by GPS receiver is present in this thesis. This is a special jamming scheme may be called cross-eye jamming. Analyze based on extensive computer simulation indicate that the execution of cross-eye jamming is of much more effect than ordinary jamming scheme.Background materials consist of chapter 1 and adaptive filter theory consists of chapter 2. Special aspect for GPS receiver adaptive processing exploitation consists of chapter 3. The cross-eye jamming scheme and its effect on adaptive filter covered chapter 4.
